Earnings per hour for washing cars = $9

Earnings per hour for walking dogs = $6

Number of hours for which car washing is done =

Number of hours taken for walking dogs =

Earnings for hours for washing cars = Per hour earnings multiplied by number of hours = $9

Earnings for hours for walking dogs = Per hour earnings multiplied by number of hours = $6

Total earnings by both = $()
