If you want to buy an item in a store that costs $15 and is on sale for 15% off, then how much would the item actually cost you

scoray [572]

Answer:

It would cost you $12.75.

Step-by-step explanation:

Model an equation, using c as the initial cost variable and x as the final cost, and then solve for x.

$x = \frac{100 - 15}{100} c \\ x = \frac{85}{100} (15) \\ x = \frac{17}{20} (15) \\ x = \frac{17}{4} (3) \\ x = \frac{51}{4} \\ x = 12.75$
