Question

Demarcus has a job washing cars. He can wash 7 cars in one hour. Which equation best represents y, the number of cars he can wash in x hours if he continues at this rate?​

Answer 1

y = 7x

Explanation:

Since we know x represents hours, and y represents the cars washed. We can make a simple equation.

We are looking for this:

Cars washed = Cars washed per hour * hours

Translating this to our variables we get:

y = 7x
