Test 2.2

Last Friday, Trevor had $29. Over the

weekend he received some money for cleaning the attic. He now has $41. How much money did he receive?

• 29 + 41 = x

• 41 - x = 29

• x + 29 = 41

• x - 29 = 41

Working together, Melissa and

Esteban collected 53 pounds of aluminum cans for recycling. If Melissa collected 20 pounds, find the number of pounds, x, that Estaban collected. Using x as your variable write an equation to solve.

• 20x = 53

• x - 20 = 53

• x - 53 = 20

• x + 20 = 53

276 people are seated in 12 identical rows for a performance of a school play. How many people are in each row? Let p be the number of people in each row.

• 12p = 276

• p + 12 = 276

• 276p = 12

• 
  

  $\frac{p}{12}\ =\ 276$

Ashley finds masking tape in packages of 4 rolls for $4.32. What is the cost of one roll in the package?

• 4x = 4.32

• 4.32x = 4

• 4(4.324) = x

• 
  

  $\frac{x}{4}=\ 4.32$

Raul paid a gym membership fee of $50, plus $20 per month. Raul has paid a total of $290 to the gym. Which equation matches this situation?

• 20m + 50 = 290

• 50m + 20 = 290

• 50 + 20 = m

• 50m - 20 = 290

Scott works on cars. He charges $35 for each car plus $7 per hour. Write an equation that represents this scenario if Kylie's car bill was $63.

• 7x + 35 = 63
• 7x = 63
• 7x - 35 = 63
• 35x + 7 = 63

• 2.5 hours

• 4.5 hours

• 7.5 hours

• 10.5 hours

Penelope is going to the carnival to ride the rides. It costs $20 to get into the carnival and ride tickets are $0.50 each. Write an equation that represents this scenario if she spends $35 in all.

• .50x + 20 = 35
• .50x = 35
• .50 + 20x = 35 
• .50x - 20 = 35

Kiari needs at least $4800 to buy her first car. She has already saved half. If she saves $50/week, what is the minimum number of weeks it will take her to save enough for the car?

Write the inequality to the problem.

• 50x+1/2 ≥ 4800

• 1/2x+50 ≤ 4800

• 50x+2400 ≥ 4800

• 50x+2400 ≤ 4800
