$31.75
$44.25
$51.53
$57.25

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**.
