Question

Apples sell for $1.90 per pound, and bananas sell for $0.75 per pound. Troy bought some apples and some bananas. Together they weighed 3.8 pounds, and cost $5.84.

Let p represent the number of pounds of apples Troy purchased.

Which equation represents the problem described here?


A.
1.15p + 2.85 = 3.8<=my answer

B.
–1.15p + 2.85 = 5.84

C.
1.9p + 0.75 = 3.8

D.
1.15p + 2.85 = 5.84

`Let p represent the number of pounds of apples Troy purchased. `


p = the number of pounds of apples
q = the number of pounds of bananas


p+q = 3.8 since `Together they weighed 3.8 pounds`


solve for q
p+q = 3.8
p+q-p = 3.8-p
q = 3.8-p

--------------------------------------

`Apples sell for $1.90 per pound`
buying p pounds of apples costs a total of 1.90p dollars


`bananas sell for $0.75 per pound`
buying q pounds of bananas costs a total of 0.75q dollars


We have 1.90p+0.75q as the total cost in dollars. The total cost is known to be 5.84, so,


1.90p+0.75q = 5.48


Now plug in q = 3.8-p
1.90p+0.75q = 5.48
1.90p+0.75(3.8-p) = 5.48
1.90p+0.75(3.8)+0.75(-p) = 5.48
1.90p+2.85-0.75p = 5.48
1.15p+2.85 = 5.48


So you are close, but not quite there.
