Use the model to write and solve an equationX + 134 = 253
or 134 + x = 253
X = 119 boys

A used book costs $17 less than the same book new. The used book costs $9. Use a bar diagram to write and solve an equation to find out how much the new book cost.
?
New book
Used book
17 9
X – 9 = 17
X = $26 for a new book
