Isabel purchased bananas and apples at a grocery store. She spent a total of $9.90 on 3 pounds of apples and 2 pounds of bananas. If the apple cost 3 times as much per pound as bananas, what is the cost per pound of apples?? A) $0.90

B) $1.80

C) $2.70

D) $3.60

C. $2.70

If one pound of apples cost 3 times the amount of a pound of bananas, then a pound of apples costs; $2.70.

Step-by-step explanation:

C) $2.70

let x be the cost of one pound of bananas

3(3x) + 2x = 9.90

11x = 9.90

x = 0.90

Price of one pound of apples = 3 x = 3(0.90) = $2.70
