Answer :
Store BBB has a better deal than store AAA.
Given the original price of the skateboard = 200$
At the store AAA offer discount on sale is 30%
So the price of the skateboard on sale is
= 200 - 30% (original price)
= 200 - (30/100 *200)
= 200 - (60)
=. 140
Now the store AAA has a reward coupon to take an additional discount of 20% offer while purchasing then
= 140 - (20% of 140)
= 140 - (20/100 *140)
= 140 - (28)
= 112
The final price of a skateboard at store AAA is 112$
Given the skateboard at the store, BBB is on sale for 50% as
= 200 - (50% of original price)
= 200 - (50/100 * 200)
= 200 - 100
= 100
The final price of a skateboard at store BBB is 100$
By comparing the two stores we conclude that store BBB is better than store AAA.
