John goes to a restaurant and has a bill of $32.57. He uses a 10% off coupon on the cost of the meal. The tax is 8%. He leaves a tip of 18% on the amount before the coupon or tax is applied. How much does he spend?

$37.51

Step-by-step explanation:

(all percents can be divided by 100 and be turned into decimals)

     First, we will read it through and we catch that the tip is before the coupon or tax, so let us find the tip first.

$32.57 x 0.18 = $5.86 (round at hundredths for money)

So, after everything else, we will add on $5.86 for the tip.

Next, let's look at the coupon. He had a 10% coupon, and only paid 90% of the meal: $32.57 x .9 = $29.31

He then pays 108% of $29.31 because of the 8% tax: $29.31 x 1.08 = $31.65

Add on the tip from the start: $31.65 + $5.86 = $37.51

Hope this helps, have a nice day :D
