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>

for solving this linear equation
First, subtract 35 from both sides.

isolate x so divide both sides by 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.

Answer:
1 3/4 cups
Step-by-step explanation:
In order to be able to equally divide the stew into 5 containers we need to turn everything into the same format, in this case it would be by multiplying the whole number and the denominator and then adding the numerator like so
(8 * 4) + 3 = 
Now we can divide the numerator by 5 (container) in order to calculate how much stew each container will get.

So each container will get 7/4 of the Stew or 1 3/4 cups
