Answer:
$1.30
Step-by-step explanation:
Let x = the cost of the pencil
Let x + .80 = the cost of the pen
Let 4(x + .80) = the cost of the binder
x + x + .80 + 4(x + .80) = 11.80
2x + .80 + 4x + 3.20 = 11.80
6x + 4.00 = 11.80
6x = 7.80
x = $1.30
x + .80 = $2.10
4(x + .80) = $8.40
2-5 x 1/2 = 0.2 (Length x Width)
4x+12=1x+60
4x+12=x+60 Move terms
4x-x=60-12 collect the like terms
Subtract
3x=48
Divide both sides by 3
X=16
