Answer:
Joe's y = 4x + 20 ($20 initial value and a rate of $4 per hr)
slope/rate is $4 per hour and the initial fee/y interceot is 20
Callie's y = 14x (no initial fee and a flat rate if $14 per hr)
slope/rate is $14 per hour and the initial fee/y intercept is 0
Substitute in 3 for x to see who's price is better for 3 hours
y = 4(3) +20 or y = 14(3)
y = $32 y = $42
Callie's has the better deal for 3 hours. Only for 1 hour Joe has the better deal. At 2 hours, both are the same price, and 3 hours plus, Callie will always be cheaper.
