Answer 1

solution:
each magazine cost 10
156 magazine without discount cost 1560
with 30% disc saving = 0.3 * 1560 = 468
so 152 magazine with disc cost = 1092
so with 1092 we get 152 magazines instead of 109 with usual price i.e . 43 magazines
52 magazine without discount cost 520
with 25% disc saving = 0.25 * 520 = 130
52 magazine with disc cost = 390
so with 390 we get 52 magazines instead of 39 with usual price i.e 13 magazines more
