a pen and pencil cost $5.00 the pen costs $4.00 more than the pencil. what is the price of each?

Answer 1

Easy. Take away the $4 that the pen costs more. That leaves $1. Divide by two = $0.50. That's the cost of the pencil. Add $4.00 to $0.50 and that's the cost of the pen'

$0.50 + $4.50 =$5.00

Answer 2

x + (x+$4) = $5.00

2x + $4 = $5

2x = $1

x = $0.50

pencil = $0.50 cents, the pen = 0.50 + 4 = $4.50
