Question

13. Tracy mowed lawns for 2 hours and earned $7.40 per hour. Then she washed windows for 3 hours and earned $6.50 per hour. What were Tracy's average earnings per hour for all 5 hours?

Answer 1

Since Tracy mowed the lawn for 2 hours and earned $7.40 per hour you would multiply 2 by 7.40 due to working for 2 hours. 2*7.40= 14.8. Next you need to do the same except for cleaning windows which is $6.50 per hour. You then multiply. 6.5*3= 19.5. Add both totals for the average earnings for all the 5 hours which would be $34.30. Hope this helped!
