Respuesta :
If Courtney wants to buy a $200 lawnmower, she should use the 15% off coupon.
Which coupon should she use?
The coupon of choice would be the option that results in the lower price of the lawnmower.
Price of the lawnmower when the $20 coupon is used = $200 - $20 = $180
Price of the lawnmower when the 15% coupon is used = (100 - 15%) x $200
0.85 x $200 = $170
