Answer:

45hours

Step-by-step explanation:

Given

Mary month earnings to be R(x)=13x+155

Josies monthly earning is given as Q(x)=9x+335

If Josie and Mary work to earn the same salary, then R(x) = Q(x)

13x+155 = 9x+335

subtract 155 from both sides

13x+155-155 = 9x+335-155

13x = 9x+180

subtract 9x from both sides

13x-9x = 9x+180-9x

4x = 180

x = 180/4

x = 45

Since  x equals the number of hours worked by Josie and Mary, this means that Josie and Mary must work for 45hours to earn the same salary
