Step-by-step explanation:
<u><em>The correct question is</em></u>
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
----> equation A
apples cost $0.60 each and pears cost $0.35 each and Thanh spent $5.60
so
----> equation B
Solve the system of equations by graphing
Remember that the solution is the intersection point both graphs
Using a graphing tool
The solution is the point (7,4)
see the attached figure
therefore
The number of apples bought was 7 and the number of pears bought was 4
