Damon buys lumber worth $562. He gets 20% contractor discount. The sales tax is 6%. his credit card gives him 2% off. How much d

faltersainse [42]

Answer:

<u>$467.05</u>

Step-by-step explanation:

The price is $562

First, 20% off of that:

562 - 20% of 562 = 562 - 0.2(562) = $449.60

Second, he has to pay 6% tax on this amount, so:

6% = 6/100 = 0.06

449.60 + 0.06*449.60 = $476.58

He won't be paying this amount, because paying through credit card will give him 2% discount on this, so:

476.58 - 0.02(476.58) = <u>$467.05</u>

<u></u>

<u>Final Price: $467.05</u>

What does this equal too

GREYUIT [131]

10/24.

If you find the LCM of the denominators, you change the denominators to that, then take the LCM / denominator and multiply the numerator by that, making 18/24 and - 8/24. subtract with the numerators: 18 - 8 = 10. the result is 10/24

Find the slope of a line that passes through the following points<br> (-1,-5), (3,-3)

svet-max [94.6K]

Answer:

$m=\frac{1}{2}$

Step-by-step explanation:

defition of slope(m) of a line:

$m=\frac{Y_b-Y_a}{X_b-X_a}$

A=(-1,-5)=(Xa,Ya) then Xa= -1 and Ya= -5

B=(3,-3)=(Xb,Yb) then Xb=3 and Yb= -3

$m=\frac{-3-(-5)}{3-(-1)} \\\\m=\frac{-3+5}{3+1} \\\\m=\frac{2}{4} \\\\m=\frac{1}{2}$

The value of Yong's investment account increases at a rate that is proportional at any time to the value of the account at that

gavmur [86]

Using an exponential function, it is found that the value of Yong's investment account after 7 years is given by:

(C) $2363

<h3>What is an exponential function?</h3>

It is modeled by:

$y = ab^x$

In which:

a is the initial value.

b is the rate of change.

Her account was worth $2000 initially, and it increases by 10%, percent every 4 years, hence, it is modeled by:

$y(t) = 2000(1.1)^{\frac{t}{4}}$

After 7 years, the amount is:

$y(7) = 2000(1.1)^{\frac{7}{4}} = 2363$

Hence option C is correct.
