If you spend $78, which of the following are the equations for this scenario? Let x = number of 8 inch pots and let y = number of 10 - inch pots.

A. y+15y=6

12x+x=78

B. x+y=6

12x+15y=78

C. x+y=78

12x + 15y=6 (78

D. x+y=6

15x+12y=78

E. No solution

Tara Lynch · Answer 1

Things we know:

Six total pots = # of 10" + # of 8"

$78 total = cost of 10" + cost of 8"

So:

6 = x + y

and

78 = x * (cost of x) + y * (cost of y)

78 = x*12 + y*15

We need:

x+y=6 AND 12x+15y=78

So our answer can only be B.
