A karate studio charges $35 for the first course and $22. 50 for each course after that, even if the student leaves the course e
VashaNatasha [74]

The Cena can take 7 courses

We have given that the karate charges $35 for the first course and $22.50 for each course after that. Our total is $170.

<h3>What is the condition we can write here?</h3>

22.50x + 35 = 170

for solving this linear equation

First, subtract 35 from both sides.

22.50x = 135

isolate x so divide both sides by 22.50.

x=\frac{135}{22.50}

Therefore we get x = 6

Remember to add the additional class, so x is actually 7.

So,the Cena can take 7 courses.
