Answer:
Step-by-step explanation:
From the information given, you can write the following equations:
x+y=300 (1)
5x+8y=300*7
5x+8y=2100(2)
First, you can isolate x in (1):
x=300-y (3)
Now, you can replace (3) in (2):
5(300-y)+8y=2100
1500-5y+8y=2100
3y=2100-1500
y=600/3
y=200
Then, you can replace the value of y in (3) to find x:
x=300-200
x=100
According to this, the answer is that he should use 100 pounds of dried pineapple and 200 pounds of dried apricots.

Part 1) 
Part 2) 
L = 220 ft2 ; S = 280.5 ft2
Step-by-step explanation:
<u><em>The correct question is </em></u>
Find the lateral area and surface area of a rectangular prism. The base is a square 5.5 ft by 5.5 ft, and the height is 10 ft
Part 1) Find the lateral area
The lateral area of a rectangular prism is equal to
where
P is the perimeter of the base
h is the height of the prism
we have
---> the perimeter of a square
---> is given
substitute
Part 2) Find the surface area
The surface area of a rectangular prism is equal to
where
LA is the lateral area
B is the area of the base
we have
----> area of a square
substitute
