Dylan bought 3 identical shirts online for a total cost of $71.83 including a flat rate of $7.99 for shipping. Which equation shows how to find the cost of each shirt, s?

• 7.99 + s = 71.83

• 7.99 + 3s = 71.83

• 71.83 + 3s = 7.99

• 7.99 + 71.73 = s

A grocery store receives a 180 pound crate containing six 10-pound bags of potatoes and an unknown number of 5-pound bags of potatoes. Which equation represents the number of bags of small potatoes, p, in the crate?

• 180 + p = 10

• p + 10 = 180

• 60 + 5p = 180

• 60 - 5p = 180

Solve the equation: 60 + 5p = 180

• p = 24

• p = -24

• p = 19

• p = 6

Natalia paid $38.95 for three medium sized pizzas and a salad. Which equation represents this situation if Natalia paid $11.98 for the salad. P represents the price of each pizza.

• 38.95 + 3p = 11.98

• 3p + 11.98 = 38.95

• p + 11.98 = 38.95

• 38.95 + 11.98 = p

Solve the equation: 96d + 206 = 782

• d = 7

• d = 5

• d = 6

• d = none of these

What is the solution to the equation:

-5(w - 30) = -10

• j = -4

• j = 8

• j = 28

• j = 32

The five members of the Traynor family each buy train tickets. During the train ride, the bill for their boxed lunches cost $32.50. If the total cost of the trip is $248.50, which equation represents how to find the cost of each train ticket, t.

• 5t + 32.50 = 248.50

• t + 32.50 = 248.50

• 248.50 + 5t = 32.50

• 248.50 - t = 5

Solve the equation:

3(x + 4) = 36

• x = -8

• x = 8

• x = 0

• x = 10.7

Five friends go see a movie and spend $8 per ticket. They also purchase a small bag of popcorn each. If the friends spend a total of $62.50, which equation shows how to find out how much each bag of popcorn, p, cost?

• 40 + 5p = 62.50

• 8 + p = 62.50

• 40 - p = 62.50

• 8p + 5 = 62.50

Solve the inequality

c - 12 > -16

• c < 4

• c > 4

• c < -4

• c > -4
