Question

A $1000 stereo is on sale for 15% off. You have a $75-off coupon.

Since we already know the price, we can easily tell whether the $75-off coupon or
the 15%-off sale is the better deal. We can express functions for both.
•
•
The cost with the $75-off coupon can be written as the function C(p) = p - 75,
where p is the price.
The cost with the 15% off sale option can be written as the function S(p) = .85p,
where p is the price.
However, what if you could apply both the coupon and the sale price to your
purchase? Consider that as you answer the question below. Show your work and
explain your thinking.
Which is the better deal? Should you use the coupon first, then take the 15% off?
Or should you take the 15% off, then apply the coupon?



ANSWER QUICKLY!!

Answer 1

15% off is the better deal

Explanation:

But if you want, I think taking 15% off is a better deal then using the coupon before so that you will still be at 850 - 75 = 825
