Jim bought 20 rose bushes last week. The regular price is $5.00 per bush, but last week they were on sale at 2 for $8.50. How much did Jim save by buying the bushes on sale?

he saved $15

Step-by-step explanation:

The regular price is $5.00 per rose bush, but last week they were on sale at 2 for $8.50. This means that the amount that one would cost is

8.5/2 = $4.25

If Jim bought 20 rose bushes last week, it means that the amount that he paid for 20 rose bushes is

20 × 4.25 = $85

The regular price is $5.00 per rose bush. If he had bought at the regular price, the amount that he would have paid is

5 × 20 = $100

Therefore, the amount saved by the bushes on sale is

100 - 85 = $15
