How much profit will a store make on the sale of a flat screen TV that is marked up by 30% and then sold at a 20% discount if th
notsponge [240]

The flat screen TV that is marked up by 30% and 20% discount had a profit of $60 after being sold.

The mark up percentage is given by:

Mark up percentage = (selling price - cost price)/cost price

Since the original price is $1500, hence:

30% = (selling price - 1500)/1500

0.3 = (selling price - 1500)/1500

(selling price - 1500) = 450

Selling price = $1950

It was again sold at a discount of 20%:

Final selling price= 1950 - 20% of 1950 = 1560

Profit = 1560 - 1500 = $60

Hence $60 profit was made by the store for the sale of a flat screen TV.

Pete, Lulu and Liza are walking in the Boston downtown. Each time Pete takes 4
Rasek [7]

If Liza takes 120 steps, then the number of steps taken by Pete will be 72.

<h3>What are a ratio and a proportion?</h3>

A ratio is an ordered set of integers a and b expressed as a/b, with b never equaling 0. A percentage is a mathematical expression in which two things are equal.

Pete, Lulu, and Liza are walking in the Boston downtown. Each time Pete takes 4 steps, Lulu takes 3 steps. Each time Lulu takes 5 steps, Liza takes 4 steps.

Then the relation between is given as

4 Pete → 4 Lulu

5 Lulu → 4 Liza

Then we have

\rm \dfrac{5}{3} \times 4 \  Pete  \rightarrow \dfrac{5}{3} \ Lulu \rightarrow 4 \ Liza

If Liza takes 120 steps, then the number of the step taken by Pete will be

\rm \dfrac{5}{3} \times 4 \  Pete  \rightarrow 4 \times 120 \\\\Pete  \rightarrow 72

More about the ratio and the proportion link is given below.

Use linear combination. To solve system <br> -2x+7y=10<br> X-3y=-3
Tamiku [17]
-2x + 7y = 10 ⇒ -2x + 7y = 10
   x - 3y = -3   ⇒ <u>-2x + 6y = 6  </u>
                                      y = 4
                         -2x + 7(4) = 10
                           -2x + 28 = 10
                          <u>         -28   -28</u>
                                   <u>-2x</u> = <u>-18</u>
                                    -2      -2
                                       x = 9
                                  (x, y) = (9, 4)

Which statement correctly describes the relationship between the graph of f(x)=2x and the graph of g(x)=f(x)-4?
irina1246 [14]
The answer is C because we can say that the x value is the input and the y value is the output therefore as the 4 is subtracted after the function the output decreases by 4 and the y values must therefore decrease by 4.
