Solve for b:

A toy company spends $1500 per day for factory expenses plus $8 to make each teddy bear. Which equation represents the total cost C spent after making B teddy bears?

• 8B = 1500

• 8B + 1500 = C

• 8B - 1500 = C

What step would you first take to solve this equation?

• Divide both sides of the equation by 2

• Subtract 2 from both sides of the equation

• Multiply both sides of the equation by 2

• Add 2 to both sides of the equation

The Roaming Cell Phone Company charges $15.00 per month plus $0.20 per minute of airtime usage. If Juanita uses x minutes of airtime, what is an equation that can be used to determine her monthly cell phone bill (C)?

• C = 0.20x + 15

• C =15 (0.20x)

• C = 15 + x + 0.20

• C = 0.20 + 15x

Sam ordered 4 tacos and 5 enchiladas for lunch at the restaurant. His bill came to $10.80. Which equation matches the given situation?

• 4x + 3y = 8.10

• 4x + 5y = 10.80

• 4x - 5y = 10.80

• 4x + 10.80y = 5

Jenny went to the sale at Kohl's last weekend.

T-shirts were on sale for $15 each and hoodies were on sale for $20 each. If she spent $150 total, write an equation to represent this situation.

• 20x + 15 = y

• 35x = y

• 15x + 20y = 150

• 150 - 20x = 15y

The Sugar Sweet Company is going to transport its sugar to market. It will cost $4500 to rent trucks plus $125 for each ton of sugar transported. The total cost, C (in dollars), for transporting n tons is given by the following.

C = 4500 +125n

If the total cost is $7125, how many tons is the company transporting?

Solve for x: 12 + 3(x + 1) = 3

Select all equations that have a solution of x=3

• 
  $\frac{4}{3}​(x+13)=12$

• 1−2(x+7)=x−13

• 12−x=0.3(x+27)

• $\frac{x}{4}​=\frac{12}{16}$
