Question

Nathan is buying a cell phone for his business. The regular price of the cell phone is $179. If he buys the phone in the next 2 weeks, he will get a 20% discount. What will be the sale price if he buys the phone tomorrow?

Answer 1

To find the amount of money being discounted from the regular price, multiply the regular price by the decimal conversion of the sale percentage. 20% = 0.2. Multiply 179 by 0.2 to get 35.8. This is the amount of money getting subtracted from the regular price to get the sale price.
179-35.8 = 143.2. 
The sale price is $143.20. 
Hope that helped you!
