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.
The answer is: [C]:

Answer:
Step-by-step explanation:
Start with where it tells you the value of x. The value of x is 3. That's given by f(x) = f(3)
Next see which one of the functions you use. x > 0 is given by x^4 - 7. Since 3 is greater than zero you use x^4 - 7
f(3) means that wherever you see an x on the right side, you put a 3.
f(x) = x^4 - 7
f(3) = 3^4 - 7
f(3) = 81 - 7
f(3) = 74
