Question

Pls help I’m really confused I’ll give you 35 pints

Find the total payment,
given the cost, sales tax
rate, and tip rate.
Cost: $35.75
Sales Tax Rate: 5%
Tip: 15%

Answer 1

The total payment is thus $35.75 plus $7.11, or $42.86

Explanation:

Note that the sales tax doesn't affect the tip. The sales tax is 5% of the cost and the tip is 15% of the before tax cost. We calculate the tax and the tip separately, then add them together and finally add this sum to the cost.

Sales tax: 5% of $35.75: $1.75

Tip: 15% of $35.75: $5.36

Adding these two quantities results in $7.11.

The total payment is thus $35.75 plus $7.11, or $42.86
