can someone help me with this. (Convert the repeating decimal to a fraction show all your work)

you cannot convert a repeating decimal into a fraction

Step-by-step explanation:

Hi tissuebox, 

let x= the number of bottles the customers buys

first, lets consider how many bottles the customer must buy for the price to be the same no matter which company.

4x+10=3x+25
.
.
.
x=15, so at 15 bottles, the cost is the same for either company. At this point you look at x=16, one bottle higher, to compare costs, seeing that for company A this is $74 while for company B this is $73, so at 16 bottles company B is cheaper
