You get paid $1.50 for every box you make. On day 1 you make 10 boxes, day 2 you make 4 boxes, day 3 you make 15 boxes and day 4 you make 8 boxes. What is your total pay?
You times 1.50 by how much you sold a day. So 1.50 times 10 you make $15. Then you do that for each day. Then when you find how much a day add all the prices up. So your answer would be 55.50.
