A board game that normally costs $30 is on sale for 25 percent off. What is the sale price of the game?
Paha777 [63]

We can use two different ways to solve this equation:

Because the board is 25 off, we can multiply the price and subtract the result:

30 - 0.25(30) = 30 - 7.5 = $22.50

We can also solve by multiplying the total price by 0.75

(1 - 0.25)(30) = 0.75(30) = $22.50

The sales price is $22.50
