1.25 - 0.5 = 0.75


1.25 hours = 1 hour 15 minutes
0.5 hours = 30 minutes

1 hour 15 minutes - 30 minutes = 45 minutes

The value of a car bought new for $28900 decreases 15% each year. Identify the function for the value of the car. Does the funct
Eva8 [605]

Answer:

<u>V (t) = 28,900 - 4,335t</u>

<u>The function clearly represent a decay</u>

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Value of the car = $ 28,900

Annual depreciation = 15% = 0.15

2. Identify the function for the value of the car. Does the function represent growth or decay?

Let y represent the value of the car after t years of utilization, let p the price of the car and d, the annual depreciation, therefore:

V (t) = p - (d * t * p)

Replacing with the values we know:

V (t) = 28,900 - (0.15 * t * 28.900)

V (t) = 28,900 - (0.15 * t * 28.900)

<u>V (t) = 28,900 - 4,335t</u>

<u>The function clearly represent a decay.</u>

a store had a sale on art supplies. the price p of each item was marked down 60%. which expression represents the new price
andrezito [222]
If the price of the item drops by 60% then that means the new price is 40% of the original

new price = p*0.4

ex: 
new price = $100*0.4= $40
new price= $75*0.4 = $30
