Answer 1

To calculate how much Isabella’s mom spent at the mini-golf park, we need to determine the total cost before applying the coupon and then apply the discount.

Here’s the breakdown of costs:

1. Adult Game: 1 game at $7.00 \[ 1 \times 7.00 = 7.00 \]

2. Child Games: 6 games at $3.50 each \[ 6 \times 3.50 = 21.00 \]

3. Pirate Hat: 1 hat at $17.25 \[ 1 \times 17.25 = 17.25 \]

4. Arcade Tokens: 30 tokens at $4.00 for 10 tokens (so for 30 tokens, it’s 3 sets of 10) \[ 3 \times 4.00 = 12.00 \]

Now we can add these amounts together to find the total cost before the coupon: \[ 7.00 + 21.00 + 17.25 + 12.00 = 57.25 \]

Next, we apply the coupon, which gives a discount of \( \frac{1}{10} \) off the total bill. To find the discount: \[ \text{Discount} = 57.25 \times \frac{1}{10} = 5.725 \]

Now we subtract the discount from the total: \[ 57.25 - 5.725 = 51.525 \]

Rounding to the nearest cent, we find: \[ 51.53 \]

Therefore, the total amount that Isabella’s mom spent at the mini-golf park is $51.53.
