Answer:
If all the items are sold, the profit percentage is 14.28%.
Step-by-step explanation:
Given that the cost of 21 articles is equal to selling price of 18 articles, to find the profit or loss percent the following calculation must be performed:
21 = 100
21 - 18 = X
21 = 100
3 = X
(3 x 100) / 21 = X
300/21 = X
14.28 = X
Therefore, if all the items are sold, the profit percentage is 14.28%.
Hi there!
c=74
<u><em>Equation:</em></u>
26+c=100
c+26=100
100-c=26
100=c+26
100=26+c
<u><em>1.Find the meaning:</em></u>
so 26 contacts and then the total would be 100 which would be 26+c=100...
<em><u>2.Subtract the two terms:</u></em>
<em><u /></em>
<em><u /></em>
Therefore, c=74
8x + 42 = 90
8x = 90 - 42 = 48
x = 48/8 = 6 answer
The answer would be D. It says the length is 10 millimeters less than TWICE the width, so it would be 10 millimeters greater than the original width.
It decreases the number of data by one.
