Linear Equations One Variable

Ace Telecommunications charges $0.12 per minute of phone use plus a monthly service fee of $8.00 for it phone service. Which equation can be used to find c, the total cost for one month when m, minutes are used?

• c = 0.12m + 8m

• c = 8m + 0.12m

• c = 0.12m + 8

• c = 0.20m

Your new job is at the Custom T Shop, where T Shirts are printed to order. For each order, Custom T Shop charges $8 per shirt plus a one time set up fee of $15, represented by the equation y=8x+15

How much would 50 shirts cost?

• y= 40

• y= 400

• y= 415

• y= 65

• y= 390

A T-shirt design company charges your team an initial fee of $25 to create the team's design. Each t-shirt printed with your design costs an additional $8. The equation for this situation is y = 8x + 25. Interpret the y-intercept in context.

• The additional fee of $8.

• The initial fee of $25.

• The additional fee of $25.

• The initial fee of $8.

Evan is going to the 50th state fair this weekend. It costs $10 to enter and each ride is $2. Create a linear function that could be used to determine how many "x" rides Evan can go on.

What does the variable "y" represent?

• the number of rides he goes on

• the total cost of going to the fair

Which of the equations fits for the word problem? Thomas had $20 to spend on seven raffle tickets. After buying them she had $6. How much did each raffle ticket cost?

• 20 - 7x = 6

• 7x + 6 = 20

• 6x + 7 = 20

• 6x - 7 = 20

Write an equation to represent this word problem.

• 24 - 7p = 10

• 24 + 7p = 10

• 24 = 7p - 10

• Can't do it

Nikievia charges $5 per hour for babysitting, plus a flat fee of $12 for her travel expenses. Yajaira charges $3 per hour for babysitting, plus a flat fee of $18 for her travel expenses. Which equation could be used to determine the number of hours each babysitter must work to earn the same amount?

Write an algebraic expression that represents:

"Eight subtracted from twice a number is negative two."

Translate the following statement into an equation. Two times the sum of a number and 5 subtracted from 3 is 10.

• 3 - 2x + 5 = 10

• 2(x + 5) - 3 = 10

• 3 - 2(x + 5) = 10

• 2x + 5 - 3 = 10

Write an equation to represent the situation
