In order to join a karate class, you have to pay $10 for registration and then $2 per class. Find the equation that determines the total amount spent. T = total, c = class

2c + 10 = T

Step-by-step explanation:

Since you already have to pay $10, then that would just be added.

Then it is $2 per class: 2c

So 2c + 10 = the total cost

2c + 10 = T

Hope this helped :)

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.
