Answer:

Anne earned $30.00 from walking the dog last month.

Explanation:

Let x = the money earned for walking the dog

Let y = the money earned for babysitting

x + y = 150

4x = y Substitute 4x for y into the first equation

x + 4x = 150 Combine like terms

5x = 150 Divide both sides by 5

x = 30

Anne made $30.00 walking the dog last month.

To find y, but substitute 30 for x into either of the two original equations.

x + y = 150

30 + y = 150 Subtract 30 from both sides

y = 120

Anne made $120.00 from babysitting last month.
