Answer:
$15
Step-by-step explanation:
$3 correspond is the 20% discount of the total price.
If the total price is x then you can express the discount as:
0.20x = 3
x = 3/0.20
x = 15
Finding the equivalent multiplier, it is found that the function for the final price is:
P(x) = 0.68x.
-------------------------------------------
- There is a holiday sale of 20% off the price of x, thus 0.8x is paid, as 1 - 0.2 = 0.8.
- Additionally, there is a coupon of 15% off, thus, 0.85 of 0.8x is paid.
- The equivalent multiplier is:

- Thus, the function for the final price is:

Step-by-step explanation:
3 = 2/3 m
m = 9/2
by the matrix property of associative: (A+B)+C = A+(B+C)
H = [-2 8 -1]
m x H = 9/2 x [-2 8 1] = [-9 36 -9/2]
