Question

A school spent $150 on advertising for a breakfast fundraiser. Each plate of food was sold for $8.00 but cost the school $2.00 to prepare. After all expenses were paid, the school raised $2,400 at the fundraiser. Which equation can be used to find x, the number of plates that were sold?

6x – 150 = 2,400

6x + 150 = 2,400

10x – 150 = 2,400

10x + 150 = 2,400

​

Answer 1

6x – 150 = 2400

Explanation:

Each plate of food was sold for $8, but cost the school $2 to prepare:

-2x + 8x = 6x

A school spent $150 on advertising for a breakfast fundraiser:

-150

After all expenses were paid, the school raised $2400 at the fundraiser:

6x – 150 = 2400

In case you want to solve it:

6x – 150 = 2400

+ 150 + 150

Answer 2

A. 6x-150=2400

X=425

Explanation:

Solve.

6x-150=2400

First, you add 150 from both sides of equation.

6x-150+150=2400+150

Then, simplify.

2400+150=2550

6x=2550

Divide by 6 from both sides of equation.

6x/6=2550/6x

Simplify to find the answer.

2550/6=425

X=425 is the correct answer.

A. 6x-150=2400 is the correct answer.
