Question

An art class cost $45 for materials and then $10 per class. Write an equation to represent the total spent for any given number of art classes.
Responses

y= 45x+10
y= 45x+10

y= 10x+45
y= 10x+45

y= -10x-45
y= -10x-45

y= -45x+10

1 answer

To represent the total spent for any given number of art classes, you need to account for both the initial fixed cost for materials and the variable cost per class.

  • The fixed cost for materials is $45.
  • The cost per class is $10, and if you have \( x \) classes, that cost would be \( 10x \).

Putting this information together, the equation representing the total spent \( y \) can be written as:

\[ y = 10x + 45 \]

So the correct response is:

y = 10x + 45
