They charge the same amount.

Happy Harry’s Laundromat

Jolly Judy’s Laundromat

Answer 1

To determine which laundromat offers the better deal, we can calculate the cost per minute for each one.

**Happy Harry’s Laundromat:**
- Cost: $1.50 for 10 minutes
- Cost per minute: \( \frac{1.50}{10} = 0.15 \) dollars per minute

**Jolly Judy’s Laundromat:**
- Cost: $2.25 for 15 minutes
- Cost per minute: \( \frac{2.25}{15} = 0.15 \) dollars per minute

Both laundromats charge $0.15 per minute. Therefore, they charge the same amount, and neither offers a better deal over the other.
