Flip-flop sets are on sale at buy one, get one half-off. Maria and
Jackie each decide to get a pair.
The flip-flops are priced at $24.00.
If they decide to split the total
evenly, then how much will each
pay?

They will both pay $12.00 each so they can get the oh so overpriced $24.00 flip-flop. By the way I know this because 12 is half of 24.

So don't take my word i'm not exactly a mathematical person but i would assume a. because while selling the soap every month you increase in sells so you would by 11 percent. the you would get the factor 0.89 which if i had to guess would be the monthly profit over 11 probably wrong tho
