Jonathan is shopping for a frame for a square painting. Each side measures 8.6 inches. What is the area (length x width) of the painting? Write an equation to model your work.

• 8.6 + 8.6 = p

  p= 17.2 inches

• 8.6 x 8.6 = m

  m= 73.96 inches

• 8.6 - 8.6 = p

  p= 0 inches

• 8.6 x 8.6 = m

  m= 73.69 inches

A bowling alley charges $148 per hour for parties. How much would a 3.5-hour party cost? Write and solve an equation.

• 148 x 3.5 = p

  p= $518

• 148 x 3.5 = p

  p= 518

• 148 + 3.5 = p

  p= $151.50

• 148 - 3.5 = p

  p= $144.5

Sara is buying party supplies. How much will 8 balloons cost if each one is $1.25? Write an equation.

Sara wants to buy 13 paddle balls, each one costing $0.79. She uses partial products to find her total. She says, “$21.90 is much more than my estimate of 13 × $1 = $13, so my estimate is too low.”

Do you agree? 10 x 0.9 = 9

10 x 0.7= 7

3 x 0.9 = 2.7

3 x 0.8 = 3.2

9 + 7 + 2.7 + 3.2 = $21.90
