Question: An average American eats 50 pounds of canned food in 120 days. How many pounds would he eat in 4 days?


A ) 2.16 pounds
B ) 1.66 pounds
C ) 1.16 pounds
D ) None of the above

Steps to derive

1 Let n represent the quantity of food an average American person eats in 4 days.

 [DaysQuantity .]
2 12050 = 4n

 [Write the cross products.]
3 120 × n = 4 × 50

 [Multiply.]
4 120n = 200

 [Divide each side by 120.]
5 120n120 = 200120

 [Simplify.]
6 n = 1.66

7 An average American would eat 1.66 pounds of canned food in 4 days.



Hence the right answer is Option B
