EOC Practice #2

  • Write an equation symbolically to express a contextual problem.


Slide3 l.jpg

1. Trevor Benjamin is a salesperson who is

paid a monthly salary of $500 plus 2%

commission on sales. Write an equation

that represents Trevor’s monthly salary.

A. S = 2x + 500

B. S = 500x + .02

C. S = .02x + 500

D. S = .05x + 2

  • Mrs. Doubtfire is planning to place a fence around her backyard. The fencing costs $1.95 per yard. She buys f yards of fencing and pays $3.50 in tax. If the total cost of the fencing is $81.50, write an equation to represent the situation.

  • A. 3.50f + 1.95 = 81.50

  • B. 1.95f + 3.50 = 81.50

  • C. 1.95 f - 3.50 = 81.50

  • D. 3.50f – 1.95 = 81.50

For questions 2 and 3, use the following information.

Dollywood first opened in 1961 as a small tourist attraction named “Rebel Railroad.” After several name changes, Dolly Parton became co-owner in 1986 and the park was renamed “Dollywood.”


Slide6 l.jpg

  • Let y represent the number of years

  • after 1961 that the park was renamed

  • Dollywood. Write an expression for the

  • year the park was renamed.

  • A. 1961 – y

  • B. 1986 – y

  • C. 1961 + y

  • D. 1986 + y

  • Mrs. Doubtfire is planning to place a fence

  • around her backyard. The fencing costs

  • $1.95 per yard. She buys f yards of fencing

  • and pays $3.50 in tax. If the total cost of the

  • fencing is $81.50, write an equation to

  • represent the situation.

  • A. 3.50f + 1.95 = 81.50

  • B. 1.95f + 3.50 = 81.50

  • C. 1.95 f - 3.50 = 81.50

  • D. 3.50f – 1.95 = 81.50


Slide9 l.jpg

  • During a one-hour episode of Numb3rs,

  • the entertainment portion lasted 15 minutes

  • longer than 4 times the advertising portion.

  • If a represents the time spent on advertising,

  • write an equation to represent the situation.

  • A. 4a + 15 = 60

  • B. 4(a + 15) = 60

  • C. a(4a + 15) = 60

  • D. a + (4a + 15) = 60


Slide10 l.jpg

  • Karen works for $6 an hour. A total of 25%

  • of her salary is deducted for taxes and

  • insurance. She is trying to save $450 for a

  • new car stereo and speakers. Write an

  • equation to represent how many hours

  • Karen must work to take home $450 if she

  • saves all of her earnings.

  • A. 6h – 0.25(6h) = 450

  • B. 6h – 0.25h = 450

  • C. 6(0.25h) = 450

  • D. 450 + 6h = 0.25(6h)



Slide12 l.jpg

paid a monthly salary of $500 plus 2%

commission on sales. Write an equation

that represents Trevor’s monthly salary.

A. S = 2x + 500

2. Let y represent the number of years

after 1961 that the park was renamed

Dollywood. Write an expression for the

year the park was renamed.

A. 1961 – y

B. 1986 – y

C. 1961 + y

D. 1986 + y


Slide15 l.jpg

3. Write an equation to represent the

year the park was renamed.

A. 1961 + y = 1986

B. 1986 + y = 1961

C. y - 1961 = 1986

D. y – 1986 = 1961
