Final answer:
To calculate the total cost of an iPhone 15 Pro with a 7.5% sales tax, multiply the original price by the sales tax rate and add it to the original price.
Step-by-step explanation:
To find the total cost of the iPhone 15 Pro with sales tax, we need to calculate the amount of sales tax and add it to the original price. First, we find the sales tax amount by multiplying the original price ($1500) by the sales tax rate (7.5%).
Sales tax amount = 1500 * 0.075 = $112.50
Next, we add the sales tax amount to the original price to find the total cost:
Total cost = $1500 + $112.50 = $1612.50
