Question

1. Your state charges 5% sales tax on nonfood items. You're buying a light bulb for $3.00, cereal for $2.50, and an orange for $.50. What will be the grand total of your bill?

Answer 1

Answer:

The total bill will be $6.15.  

Step-by-step explanation:

The problem tells us that the 5% sales tax is only charged for non-food items.  For the three items purchased, only one is non-food which is the light bulb.  The cost of the light bulb is $3.00.  In order to find the total after adding 5% sales tax, we can take the cost and multiply by 1.05, which is the original cost plus the additional 5%.  3 x 1.05 = 3.15.  To find the total bill, you need to add the cost of the light bulb, after tax, plus the cost of cereal and an orange:  3.15 + 2.50 + 0.5 = $6.15.
