Answer:
Sheldon have left 
of food.
Step-by-step explanation:
Quantity of food = 
kg
Quantity used on strawberry plant = 
Quantity used on tomato plant = 
Food left = Total - used on strawberry - used on tomato
Food left = 
Food left = 
Food left =
Therefore,
Sheldon have left of food.
Flour: 2 3/4 cups = 11/4
11/4 * 2 = 22/4 = 5 2/4 cups
Sugar: 1 1/2 cups = 3/2
3/2 = 6/4 = 1 2/4 cups
1 2/4 * 2 = 3 cups
So it *should* be 8 1/2 cups.
(25 - 10.81) - 1.38p = 10
p = package of peanuts
25 - 10.81 = 14.19
14.19 - 1.38p = 10
Subtract 14.19 from each side
10 - 14.19 = -4.19
-1.38p = -4.19
Divide both sides by -1.38
p = 3 (roughly, but because you can only buy the whole package, this is the amount you can buy)
He can buy a maximum of 3 packages of peanuts.
