A McDonald employee makes $387.50 a week. If he decides to save 10 %of that, how much money would he have left to spend?

If he decides to save 10% he decided to save 38.75 since 387.50*.10 is 387500 (move decimal 4 times to figure out what the percentage of 387.50 is since the $ already has 2 numbers after the decimals and so does. 10 which = 38.75 this is what he saves so subtract this from 387.50 to find out what he has left to spend

387.50-38.75 = 348.75
