Question

Bryce bought 32 stools that required assembly from Need-A-Seat. Some stools have three legs, and the other stools have four legs. The box arrived with 108 stool legs. If the four-legged stools cost $20 and the three-legged stools cost $15 whats the 2 equaitons using only x and y variables

Answer 1

Let x represent the number of three-legged stools and y represent the number of four-legged stools.

1) The total number of stools can be represented by the equation x + y = 32.

2) The total number of stool legs can be represented by the equation 3x + 4y = 108.

So, the two equations using only x and y variables are:

1) x + y = 32
2) 3x + 4y = 108
