Question

At a store, apples cost each and oranges cost each. Harry buys some apples and oranges and spends . He buys a total of pieces of fruit.

Answer 1

Answer:

Number of apples = 6

Number of oranges = 5

Step-by-step explanation:

At a store, apples cost $0.80 each and oranges cost $0.95 each. Harry buys some apples and oranges and spends $9.55. He buys a total of 11 pieces of fruit.

Let

Number of apples = x

Number of oranges = y

x + y = 11 (1)

0.80x + 0.95y = 9.55 (2)

From (1)

x = 11 - y

Substitute into (2)

0.80x + 0.95y = 9.55 (2)

0.80(11 - y) + 0.95y = 9.55

8.8 - 0.80y + 0.95y = 9.55

- 0.80y + 0.95y = 9.55 - 8.8

0.15y = 0.75

y = 0.75/0.15

y = 5

Substitute y = 5 into (1)

x + y = 11 (1)

x + 5 = 11

x = 11 - 5

x = 6

Number of apples = 6

Number of oranges = 5
