Erica earns money by tutoring and babysitting she always tutors for 5 hours each week, but the amount she babysit changes from week to week. Write an expression to show total number of hours Erica works in a week that she babysits for 8 hours.

8 hours

Step-by-step explanation:  

The scenario that is being described can be fully made into an equation using three variables. These would be w for the number of weeks, b for the number of hours she babysat that week, and x for the total amount of hours worked. Like so...

5w + t = x

Since we are told that we need to find the total hours worked for a single week (w = 1) and that Erica babysat for 8 hours that week (b = 8), then we only need to solve for the total amount of hours worked (x)

5(1) + 8 = x

5+8 = x

13 = x

arrange the equations with like terms in columns.

analyze the coefficients of x or y.

add the equations and solve for the remaining variable.

substitute the value into either equation and solve.

check the solution.
