Marble Middle School paid $500 for 16 graphing calculators. What was the cost for each calculator? Which equation matches the scenario?

• 1/6x = 15

• 1/6x = 500

• 500 = 6x

• 500 = -6x

Why did your teacher tell you we needed to use word problems when we solve algebraic equations?

• To annoy you

• To make you laugh

• To show real world examples

• To confuse you

I can write one-step equations to model real-world situations and

then solve the equations.

Write an equation:

A chicken lays about 250 eggs a year. If a chicken has already laid

65 eggs, how many more is she expected to lay this year?

• x+65=250

• 250+65=x

• 65x=250

• 65x+250=315

I can write one-step equations to model real-world situations and then solve the equations. Solve the equation: A chicken lays about 250 eggs a year. If a chicken has already laid 65 eggs, how many more is she expected to lay this year?

The Frederick County Fair costs $15.00 to get in and $2.50 per ride, while the Montgomery County Fair costs $10.00 to get in and $3.00 per ride. Which equations could be used to determine how many rides you would need to go on for both fairs to be of equal value?

• 15x + 2.5 = 10x + 3

• 15 - 2.5x = 10 - 3x

• 15 + 2.5x = 10 + 3x

• 15 - 10 = 2.5x + 3x

At Gamestop you can buy a Xbox One for $150.00 and each game to go with it would cost $24.00. Or, you can buy a Playstation 4 for $180.00 and each game for $20.00. Write an equation to determine how many games would need to be purchased for the cost to be equal?

• 150x + 24 = 180 + 20x

• 150 + 24x = 180 + 20x

• 180 - 150 = 24 x + 20x

• 150 - 24x = 180 - 20x
