Answer:
Pencils cost $0.12
Step-by-step explanation:
Set up a system of equations :D
let x represent pencils
let y represent pens
2x + 3y = 0.78
3x + 2y = 0.72
Because we are only interested in pencils we will solve for x first.
Isolate y in either equation, lets do the first one.
3y = 0.78 - 2x
y = (0.78 - 2x)/3
Simplify
y = 0.26 - (2x/3)
Now plug what we got into Y in the other equation
3x + 2 (0.26 - (2x/3)) = 0.72
solve by simplifying
3x + 0.52 - (4x/3) = 0.72
3x - (4x/3) = 0.20
9x/3 - 4x/3 = 0.20
lets change 0.2 into a fraction 2/10 simplified to 1/5
5x/3 = 1/5
25x/15 = 3/15
25x=3
x= 3/25 = 0.12
3^2 + 16
= (3 • 3) + 16
= 9 + 16
= 25
