Joel buys a car that orginally costs $30,000. On average, the yearly depreciation (decrease) rate is 12%. Set up an equation that can be used to find how long it will take the car to be worth half of the original value ($15,000).

s

step-by-step explanation:

let y equal to

the total fare and x is the mile of taxi ride. so the equation is

y = 0.55x + 1.75

since susie has

$10 to spend for a taxi cab, so he can have

10 = 0.55x +

1.75

x = 15 miles of

taxi ride

so the system of

inequality is

10 < 0.55x +

1.75

x > 2

i'm pretty sure the answer is a. decreases with increase in
