Answer:
A
Step-by-step explanation:
The pattern in the table adds 1.50 for ever 15 minutes. That means per minute it adds
or 10 cents. This means you multiply each minute by 0.10 to find the cost. This is the equation c = 0.10m.
Hello there!
Remember that we already have one course for $35, and $22.50 for each course after that. Our total is $170.
Our equation is:
22.50x + 35 = 170
First, subtract 35 from both sides.
22.50x = 135
Divide both sides by 22.50.
x = 6
Remember to add the additional class, so x is actually 7.
Your answer is 7 courses.
I hope this helps!
