First of all we are going to take $7.25 and multiply it by 3 here is the math 7.25 x 3 = 21.75 so this means he makes 21.75 dollars a day. since there are 365 days a year. Now i'm not saying he worked every single day but the question does not say other wise so we would take 21.75 and multiply it by 365 heres the math 21.75 x 365 = 7,938.75 this means he makes 7,938.75 dollars a year!! your welcome
