Find the total cost to the nearest cent. $110.40 summer camp; 6.5% sales tax

Answer 1

Summer camp: $110.40

Sales tax: 6.5%

____________________________________________________________

Multiply $110.40 by 6.5% (0.065).

110.40 * 0.065 = 7.176

Add 7.176 (tax) to 110.40.

110.40 + 7.176 = 117.58

____________________________________________________________

Summer camp (including tax): $117.58

Answer 2

whatever% of anything is just (whatever/100) * anything.

so the summer camp entry is $110.40, and there's a taxation of 6.5% of that, well, what is 6.5% of 110.40? well, is just (6.5/100) * 110.40, namely 7.176.

so the total cost, price and tax is 110.40 + 7.176.
