A shirt is originally priced at $24.50. The shirt goes on sale for 30% the original price. How much money, in dollars to the nea

ludmilkaskok [199]

Answer:

The final cost is 1.07($17.15) = $18.35

Step-by-step explanation:

If the discount is 30%, we can find the discounted price by taking 70% of the original price (since 100% - 30% = 70%). Substitute the equivalent 0.70 to calculate the discount price: 0.70($24.50) = $17.15. This is the discounted price.

The final cost is $17.15 times 1.07, which includes the discounted price plus the 7% tax. That final cost is 1.07($17.15) = $18.35.

Write the equation that passes through the following points:<br><br> (5,0) and (−10,−5)

Vikentia [17]

Answer:

The answer is:

$y = \frac{1}{3} x - \frac{5}{3}$

Step-by-step explanation:

❃Incase you forgot what the linear equation formula is ☟

$y = mx + b$

❃Incase you also forgot, The is what the slope formula is ☟

$m = \frac{y_2 - y_1 }{x_2 - x_1}$

➊ First: We are going to be solving for the slope.

$m = \frac{ - 5 - 0}{ - 10 - 5} = \frac{ - 5}{ - 15} = \frac{1}{3}$

➋Second: We find the y-intercept.

$y = mx + b \\ 0 = \frac{1}{3} (5) + b \\ 0 = \frac{5}{3} + b \\ \frac{ - \frac{5}{3} = - \frac{5}{3 } \: \: \: \: \: \: \: \: \: \: \: \: }{ - \frac{5}{3} = b}$

➌Third: Plug in.

$y = \frac{1}{3} x - \frac{5}{3}$

The thompson's need their garage door opener repaired. the table shows the service charge and hourly labor fees for two repair c

pentagon [3]

All you need to do here is know where and how to plug in the numbers. In each equation, you'll have an initial fee, and an hourly fee, so your equation will be
y = i + hx, where i = the initial fee, and h = the hourly fee

So, after plugging them in, here's what you get:
Doors Galore: y = 40 + 50x
G&H: y = 60 + 40x

A bulletin board has a perimeter of 200 inches. Which expression expresses the area A(w) of the bulletin board as a function of

mr Goodwill [35]

Answer:

area A(w) of the bulletin board as a function of its width, w =[100-w]*w= 100w- $w^{2}$

Step-by-step explanation:

let, the shape of the bulletin board is a rectangle,

then the perimeter of it = sum of all sides

= 2[length+width] = 2[l+w]

(let l: length, w : width )

so, 200 = 2[l+w]

100= l+w ( dividing both the sides by 2)

so, l= 100-w

area = length*width=l*w=[100-w]*w

therefore,area A(w) of the bulletin board as a function of its width, w =[100-w]*w= 100w- $w^{2}$
