Abox of a dozen fruit tarts costs 15.00. what is the cost of the one fruit tart

$15/12 = 1.25

The price of 1 fruit tart is $1.25

$1.25 each You figure this out by dividing 15.00÷12

Theirhgghh

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
