Step-by-step explanation:
To find the total cost of the computer and the television, we need to calculate the sales tax for each item and then add it to the original prices.
Step 1: Calculate the sales tax for the computer:
Sales tax for the computer = $550.00 × 0.07 = $38.50
Step 2: Calculate the sales tax for the television:
Sales tax for the television = $220.00 × 0.07 = $15.40
Step 3: Add the sales tax to the original prices:
Total cost = $550.00 + $38.50 + $220.00 + $15.40
Total cost = $550.00 + $220.00 + $38.50 + $15.40 = $823.90
The customer will pay $823.90 when purchasing the computer and the television with the 7% sales tax.
