You sign up for karate classes. the classes cost $ 8 0 $80 per month. write an equation for the number of dollars, d d, that you pay for your karate classes if you take classes for m m months. complete the table for the missing values of d d. m m d d 1 1 8 0 80 2 2 3 3 4 4 3 2 0 320

d=80m

Step-by-step explanation:

The classes cost $80. So when you start with 0 classes you have spent $0. But each month you add $80.

1$80

2$80+80

3$80+80+80

So the dollars you spend is calculated by multiplying the rate $80 by the number of months m. The equation is d=80m.

in mathematics, a function is a relationship between two variables such that the value of one of the variables, called the dependent variable, is determined by the value of the other variable, called the independent variable. there is a specific term we use to describe the set of independent variables of a function.
