Question

Jackie is selling smoothies at a school fair. She starts the day with $15 in her cash box to provide change to her customers. If each smoothie costs $3.75, which graph represents the balance of the cash box, y, after Jackie sells x smoothies?

Answer 1

The expression for the graph would be y = 3.75x + 15.

There aren't answer choices so this is the most I could do with the information provided.

Hope this at least helps you find the correct graph.

Have a nice day! :)

Answer 2

The expression for the graph would be y = 3.75x + 15.

We have given that, Jackie is selling smoothies at a school fair.

She starts the day with $15 in her cash box to provide change to her customers. If each smoothie costs $3.75

What is the slope?

A slope of a line is the change in y coordinate with respect to the change in x coordinate.

Here m= cost=slope of the given graph =3.75

We have given the constant value =$15

Therefore we get the equation of the graph is,

y = 3.75x + 15.
