Well you can see that each class costs 16 dollars...

y = 16x

where 'x' is the number of classes....so to find the cost for 6 classes...replace 'x' with 6

and at the very end....be sure to add 3 dollars for that processing fee :)

johnweldon1993 · Answer

so actually it should be

y = 16x + 3

do i solve it ?

johnweldon1993 · Answer

yes ma'am

gabylovesyou · Answer

y = 16x + 3 - 3 
y - 3 = 16x/16 
y - 3/16 = x

johnweldon1993 · Answer

no, the 'x' would be where you replace with the number of classes..

y = 16x + 3

you want to find out how much it would cost to take 6 classes... so all you would do is replace 'x' with 6 to find the cost 'y'

y = 16(6) + 3

what does 'y' = ...?
