A pencil and ruler cost 1.50 together. The ruler is 1.00 more. How much is pencil

Pencil + Ruler = 1.50

Ruler is exactly 1.00 more so one of the items has to be 1.25

1.25 - 1.00 = 25

Ruler costs 1.25; Pencil costs 25

Ok so the solution which greenrune will (hopefully) correct

total is 1.5

p+r=1.5

rule is 1 more than pencil

r=1+p

sub 1+p for r

p+1+p=1.5

2p+1=1.5

minus 1 from both sides

2p=0.5

divide both sides by 2

p=0.25

pencil=$0.25
