I’m thinking it’s $100. I guessed 100 first as that is a pretty common number and subtracted 61.75. I was left with 38.25 and I divided that by 3, the amount of washes. I got $12.75 but I had to check since I guessed 100. I then subtracted 23.50 from 100 and got 76.5. I divided that by 6, the amount of washes, and got 12.75 again. So I’m pretty sure that there was $100 on the gift card before he washes his car six times, each wash being $12.75.
The increase percentage is 50 percent because the new value is greater than the old value.
