Answer:

$\large \boxed{\$1200.00}$

Step-by-step explanation:

Let the office charge = x

Amount paid by Medicare = ⅞x

Amount paid by Ross = ¼(⅞x) = $262.50

Solve for x

$\begin{array}{rcrl}\dfrac{1}{4} \left(\dfrac{7}{8}x \right ) & = & \$262.50 & \\\dfrac{7}{32}x & = & \$262.50 & \text{Multiplied the fractions}\\\\7x & = & \$8400.00 & \text{Multiplied each side by 32}\\x & = & \mathbf{\$1200.00} & \text{Divided each side by 7}\\\end{array}\\\text{The office wanted to charge } \large \boxed{\mathbf{\$1200.00}}$

Check:

$\begin{array}{rcl}\dfrac{1}{4} \left(\dfrac{7}{8}\times \$1200.00 \right ) & = & \$262.50\\\\\dfrac{1}{4} \left(\$1050.00 \right ) & = & \$262.50\\\\\$262.50 & = & \$262.50\\\end{array}$

OK.

Given; g(x)= 8x - 2<br> What is the value of g⁻¹(30)

KiRa [710]

Answer:

$g^{-1}$ (30) = 4

Step-by-step explanation:

g(x) = 8x -2

Let g(x) = y

y = 8x -2 (note: y is the range and x is the domain, we need to rearrange to make x the range and y the domain instead)

y + 2 = 8x

x = (1/8) (y + 2)

hence the inverse of g(x) is $g^{-1}$ (y) = (1/8) (y + 2)

$g^{-1}$ (30) = (1/8) (30 + 2) = 4

The formula P=nc-e gives the profit p when a number of items n are each sold at a cost c and expenses e are subtracted. If p=570

m_a_m_a [10]

1.65

You can substitute in the values of p, n and e to get the equation:
5700 = 4000c - 900

add 900 to both sides and you get

6600 = 4000c

divide both sides by 4000 and you get

1.65 = c

so the answer is 1.65

Answer:

p = 3x+10

Step-by-step explanation:

The attached diagram pretty much explains it.

The unknown dimension at the top was the subject of a previous problem. It is the difference in length between the two marked horizontal segments:

(2x +15) -(x) = x +15 . . . . . length of unmarked solid horizontal line

Similarly, the length of the unmarked vertical line on the right is the difference between the marked vertical lines:

(2x -5) -(x -5) = x . . . . . length of unmarked solid vertical line

The formula for the area of a rectangle is used to find the areas of the left-side and right-side rectangles. Respectively, those areas are ...

left-side area = x(2x -5)

right-side area = x(x +15)

Then the total area enclosed by the solid line is ...

x(2x -5) +x(x +15) = x(2x -5 +x +15) = x(3x +10)

__

The area of the lot extension is the product of its dimensions:

extension area = x·p

We want this to be the same as the area in the solid line, so ...

x·p = x·(3x +10)

Dividing by the coefficient of p (which is x), we have ...

p = 3x +10
