Answer 1

Answer: Option a

Given : 0.01 ounce of aluminium used per square inch.

$0.40 per pound is the amount recieved for recycling tea can.

Find : the amount recieved for recycling 24 iced tea cans.

Step-by-step explanation:

Step 1 : the formula to find volume of a cylinder is

formula = 2*pi*r*h

volume = 2 x 3.14 x 1.5 x 7

= 65.94 sq inches.

Step 2 : find the total volume of 24 iced tea cans

65.94 x 24

= 1582.56 sq inches

Step 3 : find the weight in ounce with respect to square inches

1582.56 x 0.01

= 15.8256 ounces

Step 4: convert ounces into pounds

15.8256 / 16

=0.9891 pounds

Step 4: for 1 pound $0.40 is recieved so calculate for 0.9891 pounds

1/0.40 = 0.9891/y

y = 0.3856

= $0.38.

Conclusion : Hence the answer is Option a
