algebra help please

Question

Laykin earns money babysitting. she earns $5 an hour. Write an equation when y, the total she earns is a function of x, the number of hours worked.

Answer 1

Rad, I know it's confusing when we start adding the alphabet to math, but it's actually pretty simple. Let's say she worked 3 hours. She makes 5(3) = 15, right? Boom.

 

In algebra, we turn it around.

 

y = 5x

 

That's your answer. The number of hours she works, x, is going to change how much she makes, y.
