The value of a new car decreases by about 15% in the first year. How much will a car be worth after one year if its initial valu
zvonat [6]

Answer:

After one year, the car will be worth $1,275.

Step-by-step explanation:

We know that a new car value decreases by 15% every year. So, we first need to find 15% of $1,500.

1,500 x 0.15 = $225.

Now, me must subtract $225 from the initial value, or $1,500.

1,500 - 225 = $1,275

Therefore, after one year, the car will be worth $1,275.

Hope this helps! :D
