Mike earns $15 for each hour he work plus a $25 bonus. How much does he earn in 10 hours of work?
MakcuM [25]
<h3>Hello there!</h3>

We are trying to find how much Mike earns when he worked for 10 hours

Lets make an equation out of the given information in the question.

We know that:

  • Earns $15 each hour
  • $25 bonus

We would format it as y = mx + b

Our equations would be y = 15x + 25

"x" being the amount of hours he worked

We know that he worked 10 hours, so we would plug 10 into x.

Then, we can solve.

y = 15(10) + 25

y = 150 + 25

y = 175

<h3>Answer: $175</h3><h3>I hope this helps!</h3><h3>Best regards,</h3><h3>MasterInvestor</h3>
