PLEASE HELP ME :(
The formula for finding the present value of an item that depreciates yearly is v=c-crt. In this formula, v is the present value, c is the original cost, r is the rate of depreciation per year, and t is the number of years that have passed. After 4 years, what is the value of a car originally costing $30,000 that depreciated at a rate of 0.1 per year?
The value of the car after 4 years is ??

they will manufacture 8496 cars

eww xbox also eww dayz

step-by-step explanation:

just for that im not answering

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
