Question learning page tammy purchased a prepaid phone card for $30. long distance calls cost ll cents a minute using this card. tammy used her card only once to make a long distance call. if the remaining credit on her card is $27.14, how many minutes did her call last?

She called for $2.86 so just divide that by $0.11

I’m not sure what it is i sorry : ((

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
