Respuesta :

Answer: Austin spent $7.2 on his second trip to the Apple Emporium

Step-by-step explanation:

Austin paid $1.10 for two Jonagold apples. This means that the cost of one Jonagold apple is

1.10/2 = $0.55

He paid 6.75 for nine Gravenstein apples. This means that the cost of one Gravenstein apple is

6.75/9 = $0.75

He paid $3.85 for seven Rome Beauty apples. This means that the cost of one Rome Beauty apple is

3.85/7 = $0.55

Austin then decided to return to the Apple Emporium to purchase four more Jonagold apples, three more Gravenstein apples, and five more Rome Beauty apples.

Amount spent on four more Jonagold apples is

0.55 × 4 = $2.2

Amount spent on three more Gravenstein apples is

0.75 × 3 = $2.25

Amount spent on five more Rome Beauty apples is

0.55 × 5 = $2.75

The amount that Austin spent on his second trip to the Apple Emporium is

2.2 + 2.25 + 2.75 = $7.2
