Answer:

The number of apples bought was 7 and the number of pears bought was 4

Step-by-step explanation:

The correct question is

Thanh bought 11 pieces of fruit and spent $5.60. If apples cost $0.60 each and pears cost $0.35 each, how many of each kind of fruit did he buy?

Let

x ---->the number of apples bought

y ----> the number of pears bought

we know that

Thanh bought 11 pieces of fruit

so

[tex]x+y=11[/tex] ----> equation A

apples cost $0.60 each and pears cost $0.35 each and Thanh spent $5.60

so

[tex]0.60x+0.35y=5.60[/tex] ----> equation B
