Answer provided by our tutors
let
x = the cost of the one-inch binder
y = the cost of the two-inch binder
Abigail selected 3 one-inch binders and 1 two-inch binders, which cost a total of $14
3x + y = 14
Kendall selected 5 one-inch binders and 2 two-inch binders, which cost a total of $25
5x + 2y = 25
by solving the system of equations
3x + y = 14
5x + 2y = 25
we find
x = $3
y = $5
