Brent purchased a used vehicle that depreciates under a straight-line method. The initial value of the car is $7500, and the sal

Ilia_Sergeevich [38]

Let the value of the vehicle be described by the equation
V = a + bx
where x = number of years since purchase
a,b are constants.

When x = 0, V = $7500. Therefore
a + b*0 = 7500
a = 7500

When x = 7, V = $500. Therefore
7500 + 7b = 500
7b = 500 -7500 = -7000
b = -7000/7 = -1000

The equation is
V = 7500 - 1000x

The slope of this equation is the depreciation rate, and it is -$1000 per year.

Answer: $1000 depreciation per year.

A pile of 42 coins worth $4.90, consisting of nickels and quarters. How many nickels are there?

Ymorist [56]

Answer:14

Step-by-step explanation:

A nickel is 5 cents (20% of dollar)

and a quarter is 25 cents (25% of dollar)

We have given a pile of 42 coins worth of $4.90

Let x be the no nickels and

y be the no of quarter

therefore

x+y=42 -----1

$\frac{x}{4}$ + $\frac{y}{20}$ =4.90 ---2

Solving $\left ( 1\right )&\left ( 2\right )$ we get

x=14 & y=28

Therefore no of nickels is 14 & no of quarters is 28
