So we know that there are 12 inches in a foot. With this information we can do this:4 \frac{9}{12} But if you look you can see that the fraction is not simplified. How can we simplify it? Well, what is the Greatest Common Factor of 9 and 12? Well, the answer is 3! So divide 9 and 12 by three! SO the answer would be: 4 \frac{3}{4} I hope this helps!

Store A has a weekend sale. To the nearest hundredth of a percent, what discount must Store A offer for you to buy the system th
Ad libitum [116K]
We are given the cost of the product along with the markup percentage.  The markup is how the store makes a profit.  To figure out the markup price, simply multiply the "cost to store" by 100% plus the markup percent.

So the markup prices per store is:

A = 162 * 1.4 = $226.80
B = 155 * 1.3 = $201.50
C = 160 * 1.25 = $200.00

Clearly, the best deal is store C.  So in order to choose store A, we want to pay less than the price of Store C, $200.  So if Store A cost $199.99, then we would purchase there instead of Store C.

Therefore, $226.80 - $199.99 = $26.81
If Store A offered a discount of $26.81, we would purchase from Store A.

$26.81/$226.80 = 0.1182

So we would need a discount of 11.82% from Store A.

nataly862011 [7]
For this question, all we are going to do is plug all 5 of those numbers into the function f(x) = 3x.

The numbers we're given are {3, 4, 6, 7, 9} So lets plug them in!
3*3=9
3*4=12
3*6=18
3*7=21
3*9=27

So the answer is {9, 12, 18, 21, 27}! If you have any questions I'd be happy to help!
