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.
