Question

Mrs. Lowry is ordering car decals for each family to put on their cars for the upcoming baseball season. She ordered 25 decals. She got a deal on them and they will be $2 cheaper for each decal. The total came to $250. Write an equation to find the amount, d, for the normal cost of each car decal without the deal. What is the normal cost of each decal without the deal?

Answer 1

• 25(d -2) = 250
• $12 without the deal

Explanation:

You want an equation and its solution for the regular price of car decals (d) if 25 of them are sold at a $2 discount for $250.

Equation

If d is the regular price, the d-2 is the discounted price. The cost of 25 discounted decals is ...

25(d -2) = 250 . . . . an equation for finding d

Normal cost

We can divide by 25 to begin solving the equation:

d -2 = 10

d = 12 . . . . . . add 2

The normal cost of each decal is $12.
