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

### 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 = $<<5*2.50=12.50>>12.50
5 petunias at $1.00 each is 5*1 = $<<5*1=5.00>>5.00
All total, the purchase came to 12.50+12.50+5.00 = $<<12.50+12.50+5.00=30.00>>30.00
10% discount on the purchase is 30*.10 = $3.00
The purchase total, with the discount, is 30-3 = $<<30-3=27.00>>27.00
If he pays with a $50 bill, he will receive 50-27 = $<<50-27=23>>23 in change
