Final answer:
To find the customer price for a t-shirt costing the shop $16.88, add $3.75 to the shop's cost and double the total, resulting in a selling price of $41.26 before tax.
Step-by-step explanation:
To calculate the cost of a t-shirt that the souvenir shop sells, we need to follow the given two-step process.
- First, add $3.75 to the shop's cost price of the t-shirt.
- Then, double the resulting amount to get the final selling price.
Let's apply these steps to find out how much a customer will pay for a t-shirt that costs the souvenir shop $16.88 before tax:
- Add $3.75 to the shop's cost: $16.88 + $3.75 = $20.63.
- Double the amount obtained: $20.63 Ă— 2 = $41.26.
Therefore, before any tax is added, a customer will pay $41.26 for a t-shirt that costs the souvenir shop $16.88.
