Take text from a cell and add it to a new cell

Question

Here's what I'm trying to do.  I have a report that's automatically created in 2 columns.  Item and Price.  I have no way of changing how this report is made, which is why i need Numbers to help me out.  In the item column, part of the text includes a number. 
Example:
Item
Price
Large Espresso (1.4)
$1.49
Small Espresso (0.9)
$0.99
What I would like to do (if possible) is have NUMBERS put the number from "column a" into "column c"  i'm assuming it's some type of [if this cell has a number, take that number and insert it here] function
Example:
Item
Price
Amount
Large Espresso (1.4)
$1.49
1.4
Small Espresso (0.9)
$.99
.9
And then (i know i'm asking a lot but that's why i'm here to get help):
if i had multiple items all with different amounts is there a way to categorize/sort those so i could see how much of each one i have sold?  I'm assuming it's some type of [if "column a" contains (large espresso) add it's sisters "column c" together. 
Example:
Item Name
Price
Amount
Large Espresso (7.17)
$90.00
7.17
Small Espresso (1.12)
$15.00
1.12
Small Coffee (3.66)
$45.00
3.66
Small Espresso (1.10)
$15.00
1.10
Small Espresso (1.19)
$15.00
1.10
Large Coffee (2.10)
$3.50
2.10
Large Espresso (3.60)
$45.00
3.60
Large Coffee (3.60)
$45.00
3.60
Large Coffee (3.60)
$45.00
3.60
Can it sort to...
Item Name
Price
Amount
Large Espresso
(all items from above table named large espresso, regardless of what number comes after it)
$135
(total of all items named Large Espresso)
10.77
(total of numbers next to Large Espresso in "Column A")
Small Espresso
(all items named small espresso, regardless of what number comes after it)
$45
(total of all small espresso purchases)
3.32
(total of numbers next to Small Espresso in "Column A")
Large Coffee
(all items named large coffe)
$93.50
(total of all large coffee purchases)
9.3
(total of numbers next to Large Coffee in "Column A")
Small Coffee
(all items named small coffee)
$45
(total of all small coffee purchases)
3.66
(total of numbers next to Small Coffee in "Column A")
I'm sorry for such the lengthy explanation, but i tried to be as detailed as possible.  If there's any questions, feel free to ask, thank you all so much for your help, i don't know where else to turn...

Answer 1

Thank you SOOOOOO much for your help wayne, everything worked perfectly except for one thing.  It isn't returning anything to me on the summary table.  **UPDATE** Our tables were named differently, I was able to figure out how to change what columns you were referencing and add the "amount" column to my summary table by copying and pasting the previous formula and again changing what columns it referenced.  I can't thank you enough for your help! 
I do have one more question i hope you could help me with...I realize that the names in the summary table column "a" must exactly match the column "d" in the inventory list table, but if i had 2 items named the same thing could it include all text that included the item name...
Example Summary Table:
Item
Price
Amount
Large Coffee
$15.00
5.64
Small Coffee
$45.00
21.45
Large Espresso
$20.00
5.67
Small Espresso
$15.00
9.4
Changing this instead to Include all items containing the word "coffee" or "espresso" respectively.  It's ok if i have to manually write the names of the items in column "a" of the summary table, and just change the formula in the price and amount column to search for a certain word...
To make sure I'm clear, referencing the original sales sheet, and then assuming the above summary table was a result of that sales sheet, I would like only one row of coffe and one row of espresso.  So the formula would need to search for a word rather than referncing that "d" column from the earlier formulas you gave me.
Item
Price
Amount
Coffee
$60.00
(All Coffees sold, large or small)
27.09
(All Coffees Sold, large or small)
Espresso
$35.00
(All espressos sold, large or small)
15.07
(All espressos sold, large or small)
Thanks for all your help, i hope i was clear enough again
