Tina sold cookies at her clubs bake sale. she spent $18.50 on supplies. she sold her cookies for $0.75 each and made a profit of $24.25. write and solve an equation to find how many cookies tina sold.

Let x = number of cookies sold

Equation: 0.75x - 18.50 = 24.25

add 18.50 to both sides of the equation
                0.75x = 42.75
divide both sides of the equation by 0.75
                x = 57
Tina sold 57 cookies.

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
