Raina sold t-shirts at a festival. She made $6 for each t-shirt she sold. Her expenses were $30 . If she made a profit of $84 , how many t-shirts did she sell?

A. Write an equation that could be used to answer the question above. First, choose the appropriate form. Then, fill in the blanks with the numbers 6,30 , and 84 . Let x represent the number of t-shirts.

B. Solve the equation in part (a) to find the number of t-shirts.
x =

A. The appropriate equation is:

6x - 30 = 84

B. To solve for x, we'll add 30 to both sides of the equation:

6x - 30 + 30 = 84 + 30

Simplifying:

6x = 114

Finally, we'll divide both sides by 6 to isolate x:

x = 19

So Raina sold 19 t-shirts.
