Andrew bought a camera on sale at a 20% discount. It was marked down from its regular price of $120. If there is an 8% sales tax on the sale price, how much did Andrew pay for the camera?

That's pretty straight forward if you understand what percentages are! 20% of \$240 is 0.20 times 240= \$48. Since \$240 is discounted by that much, the sale price is \$240- 48= \$192. 8% of that sales price is 0.08 times \$192= \$15.36. Add that tax to the sales tax: \$192.00+ 15.36= \$207.36.
