Rhonda and Shalene live together in an apartment, so they combine their income each week to pay for their rent and bills. Rhonda's paycheck is modeled by the function r(x) = 22x + 50, where x is the
number of hours worked. Shalene's paycheck is modeled by the function s(x) = 30x – 25, where x is the
number of hours worked.
Which function represents their household income if they work the same number of hours?
A. (s - r)(x) = -8x + 75
B. (r + 3)(x) = 52x + 25
C. (r + s)(x) = 52x + 75
D. (r - 5)(x) = 8x - 75

11/15cuz both numbers have the same lcd, which is 2. you divide both by two and get 11/15. they don't have another same lcd, so you keep it that way.
