Answer:
The sale price is $37.02.
Step-by-step explanation:
With the information provided, you can find the sale price by calculating 33% of the price which is the discount and subtracting that amount from the price:
$55.25*33%=$18.23
$55.25-$18.23=$37.02
According to this, the answer is that the sale price is $37.02.

Step-by-step explanation: all you have to do is work it out
At regular price the 10 candy bars would cost $5.90 (0.59×10=5.90). At the sale price the 10 candy bars cost $4.95 (0.99×5 = 4.95). So you would save $0.95 (as 5.90-4.95 =0.95).
Use distance formula to get a distance function in terms of x representing the distance from a point on curve (x,y) to point (3,0)
y = 8/x
Minimize the function by setting derivative equal to 0.
Simplify and solve for x
This becomes a 4th degree polynomial, you can use graphing calculator to find zeros.
Also intuitively you can recognize that 64 = 4^3, so if x=4 you get
1 = 1
Therefore x=4 is a solution, substituting give y =2
