Answer:

Second and third option.

Step-by-step explanation:

The initial cost is $20 with an additional $3 per class, so:

20 + 3 * each class

In equation for this is:

20 + 3x

This means that the second and third option are both correct.

Hope this helps!

The equation represents the relationship is y = 3x +20

The amount that Lucy paid to join the fitness class represents her fixed cost. Fixed cost is the cost that does not change with he number of classes she takes.

The amount Lucy pays per class is her variable cost. Variable cost increases with the number of classes she attends.

Her variable cost can be presented with the expression : $3 × x. Where x represents the number of classes she takes.
