Abank is offering 2.5% simple interest on a savings account if you deposit $5000 how much interest will you earn in 6 months

Ithink the answer is a.3: 1i hope this

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
