The 20th visitor will be the first to get both the key chain and the bumper sticker, I found this out by finding the least common multiple, or LCM, you do this by writing out the multiples of both 4 and 10, 4 8 12 16 20..... and 10 20 30... then you find the smallest number that both 4 and 10 have in common. I hope this helps, sorry if it doesn't.

A suit is on sale for 72% off. The sale price is $263.20.<br> What is the regular price?
Elis [28]

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>
