Answer:
940
Step-by-step explanation:
<em>To find the original price of something that been discount do the following:</em>
- <em>Subtract the discount from 100 to get the percentage of the original price.</em>
- <em>Multiply the final price by 100.</em>
- <em>Divide by the percentage in Step One.</em>
<em>Or we can do the following:</em>
<em>We shall consider the original price as x; hence the discount can be considered as (x−263.20). We can write the equation:</em>
<em>x · 72/100=x - 263.20</em>
<em>x · 18/25 = x - 263.20</em>
<em>Multiply both sides by 25</em>
<em>18x = 25(x - 263.20)</em>
<em>Open the brackets.</em>
<em>18x = 25x-6580</em>
<em>Add 6580 to each side.</em>
<em>6580 +18x = 25x</em>
<em>Subtract 18x from each side.</em>
<em>6580 = 7x</em>
<em>Subtract 7x from each side.</em>
<em>x = 940</em>
<em>Check Answer:</em>
<em>940 * 72% = 676.80</em>
<em>940 - 676.80=263.20</em>
<em>Hence, the regular price is 940.</em>

Answer:
Option C is correct.
The value of r=0.2 represents the weakest correlation.
Step-by-step explanation:
Strongest correlation states that a linear relationship is indicated by a correlation coefficient of -1 or 1.
Weakest correlation states that a linear relationship is indicated by a correlation coefficient equal to 0 or if the value is nearest to 0, then it also represents the weakest correlation.
From the options, the only r-value that is very close to 0 is 0.2.
Therefore, the r-value represents the weakest correlation is, 0.2
Answer: Let x represent the cost of one of Tanya's items.
Then the cost of one of Tony's items =x - 2.25. But we have:
3x =4(x - 2.25)
3x =4x - 9 subtract 3x from both sides
0 =x - 9 add 9 to both sides
x=$9 The cost of one of Tanya's items
27 Total cost of Tanya's 3 items
2.25 =$6.75 cost of one of Tony's items.
27 Total cost of Tony's 4 items.
3 x 6.75 =$27. This shows that both Tony and Tanya spent the same amount of money.

Answer:
Step-by-step explanation: Sub -3 into where all the u’s are. So it would be
(-3)^2 - 2(-3) + 4
Which would equal 19
