Question

Lee works at a job where her pay varies directly with the number of hours she works. Her pay for 6.5 hours is 49.40. Write a direct variation equation relating lee's pay x to the hours worked y. Then find her pay if she works 25 hours in a week

Answer 1

X = pay and y = hours worked
direct variation equations are of the form:
dependent variable = k(independent variable)
we need to find k, the constant of variation
x = ky
49.40 = 6.5k
7.6 = k
EQUATION: x = 7.6y
PAY for 25 hours: x = 7.6(25) = 190 or $190
