To calculate how much Isabella’s parents spent at the mini golf park, we first need to determine the total cost of the items they purchased:
-
Cost of Adult Games:
- They purchased 2 adult games at $7.00 each.
- Total cost for adult games = 2 × $7.00 = $14.00
-
Cost of Child Games:
- They purchased 3 child games at $3.50 each.
- Total cost for child games = 3 × $3.50 = $10.50
-
Cost of Arcade Tokens:
- They purchased 20 arcade tokens where 10 tokens cost $4.00. Therefore, 20 tokens will cost double that.
- Cost for 20 tokens = 2 × $4.00 = $8.00
Now, we will sum up all these costs: \[ \text{Total cost} = \text{Cost of Adult Games} + \text{Cost of Child Games} + \text{Cost of Arcade Tokens} \] \[ \text{Total cost} = 14.00 + 10.50 + 8.00 = 32.50 \]
Next, Isabella has a coupon for 1/10 off the total bill. This means she can reduce the bill by 10%.
To calculate the discount: \[ \text{Discount} = \frac{1}{10} \times \text{Total Cost} = \frac{1}{10} \times 32.50 = 3.25 \]
Now, subtract the discount from the total cost: \[ \text{Final amount spent} = \text{Total Cost} - \text{Discount} = 32.50 - 3.25 = 29.25 \]
Therefore, Isabella’s parents spent $29.25 at the mini golf park.
