Question

A tennis racket at at sport city costs $180 and is discounted 15% the same model racket costs$200 at tennis world and is on sale for20% off which store is offering the better deal?

Answer 1

15% of 180 is (180 * 0.15) = 27.

180 - 27 = $153 paid.


20% of 200 = (200 * 0.2) = 40.

200 - 40 = $160 paid.


Therefore Sport City offered the better deal.

Answer 2

please do not ask questions twice, just wait till someone answers it

so
100-15=85
discount 15 is the same as finding 85%

100-20=80
20% off is the same as finding 80%


180*.85=153
200*.80=160

153<160

sport city is better deal
