Exercise 24 Page 593

Call the number of apples $x$ and the number of pears $y .$

$4$ pears and $7$ apples

Practice makes perfect

Let's call the number of apples Thanh bought

x .

The number of pears he bought we will call

y .

Since he bought

11

pieces of fruit in total, we can write the following equation.

x + y = 11

From the exercise we also know that apples cost

$ 0.60

each and pears cost

$ 0.35

each. The total cost for his purchase was

$ 5.60 .

With this information we can write a second equation describing the cost.
