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!
One expression could be.... Nine times 4 plus five equals forty one. ALSO... Eight times eight equals sixty four then subtract twenty four equals forty one
