Below is an instruction that describes a task. Write a response that appropriately completes the request in French. Please answer in French.

### Instruction:
 Simon wanted to buy flowers that his mom could plant for Mother's Day. The garden center was offering 10% off all purchases. He bought 5 pansies at $2.50 each, one hydrangea that cost $12.50, and 5 petunias that cost $1.00 each. If he paid with a $50 bill, how much change would Simon receive back from his purchase?


### Response:
 5 pansies at $2.50 each is 5*2.50 = $12.50.
5 petunias at $1.00 each is 5*1 = $5.00.
All total, his purchase was 12.50+12.50+5 = $30.00
10% off all purchases is 30*.10 = $3.00
His purchase was $30.00 and he had a $3.00 discount which made his purchase total 30-3 = $27.00
He paid with a $50.00 bill so 50-27 = $23.00
