CC3 Chapter 5 Review

It's the end of the semester and the clubs at school are recording their profits. The Math CLub started with $15 and increased it's balance by $10 a week. The History Club saved $5 per week and started the semester with $40. Write an equation for both situations and choose the correct answer below.

• Math Club- y = 10x+15

  History Club- y = 40x + 5

• Math Club- y = 10x+15

  History Club- y = 5x + 40

• Math Club- y = 15x+10

  History Club- y = 40x + 5

• Math Club- y = 15x+10

  History Club- y = 5x + 40

Rehman and Lauren are starting summer jobs by washing cars. Rehman charges $15 and an additional $1 per window. Lauren charges $5 and an additional $2 per window. Using the information provided, write a rule for both Lauren and Rehman.

• Lauren- y= 5x + 2

  Rehman- y = 15x +1

• Lauren- y= 2x + 5

  Rehman- y = 15x +1

• Lauren- y= 2x + 5

  Rehman- y = x +15

• Lauren- y= 5x + 2

  Rehman- y = x +15
