Linear Equation Review (Easy)

1.     A tutor charges a flat fee of $20 for a consultation. She also charges $35 per hour for tutoring. Write an equation to find the total charge, y, based on the number of hours of tutoring, x.

• y = 35x + 20

• y = 20x + 35

• y = 35x - 20

• y = 35 - 20x

Jake is working out at the gym. In the first week, he works out for 20 minutes each day. By the fourth week, he works out for 50 minutes each day. Write an equation to represent the number of minutes James works out daily, m, in relation to the number of weeks, w.

• m = 10w - 10

• m = 10w + 10

• m = 10w

• m = 10 + w

Sarah receives a basic salary of $450 per week and earns an overtime pay of $30 per hour. Write an equation in slope-intercept form for her total pay, p, if she works h hours of overtime.

• p = 450h + 30

• p = 30h - 450

• p = 30h + 450

• p = 450 - 30h

Maria earns a weekly salary of $550, and her overtime pay rate is $18 per hour. Write an equation in slope-intercept form for her total pay, p, if she works h hours of overtime.

• p = 550h + 18

• p = 18h

• p = 550 - 18h

• p = 550 + 18h
