So if 2 people were working a job that paid 7.50 an hour, and worked 42 hours a week, how much money would they make together in a year?

They would make 32,760 together in a year. One person would make 7.50 a hour times 42 hours, which would be 315 a week. You would times that by 52 weeks in a year and get 16,380 for one person per year. Multiply 16,380 by two people and you would find that they make 33,760 a year.

When i did the math i got 11 cm

Did u want to find the value of x?
