Question

Marcy makes $10 for each dog she walks. Write an expression to find how much she earns.

Answer 1

y = 10x

Explanation:

y is the variable for the total amount of money she makes, and x is the variable for the number of dogs she walks.

If each dog she walks earns her $10, then 2 dogs = $20, 3 dogs = $30, etc. Substitute the number of dogs she walks for x and multiply by 10 to find what Marcy makes.
