Jason needed to string 450 guitars. He strung 30 guitars per day for 5 days. After that, his boss told him he had 6 more days to finish stringing the rest of the guitars. How many guitars did he string per day for the rest of the time?
Figure out how many guitars Jason had finished stringing before his boss talked to him.
30 × 5 = 150 guitars finished
Subtract this from the total number of guitars he needed to string to figure out how many he had remaining.
450 – 150 = 300 guitars remaining
Divide this by the number of days he had left to complete the guitars to figure out how many guitars he needed to string per day.
300 ÷ 6 = 50 guitars per day
