The sale price of 3 bottles of shampoo is 3s and the regular price is 3r. The amount of money you save will only come in when you buy 3. The cost you save is the difference between the regular price and the sale price. The equation is therefore,
c = 3r - 3s
Answer: 
Step-by-step explanation:
The perpendicular slope of the line(m) = 
:
- m = -4 ⇒
The function formula is y = mx + b, where the y-intercept(b) is found by substituting in the values of a point on the line ⇒ (4, -6):
<u>So the perpendicular equation is </u><u>.</u>
The total number of possible combinations to make a three digit number is 60
<u>Explanation:</u>
Given:
Five numbers are there = 1, 2, 3, 4, 5
We have to form three digit number
The number should not be repeated
Consider 3 dashes for 3 digits : ___ ___ ___
The first dash can be occupied by any 5 digits.
The second dash can be occupied by 4 digits
The third dash can be occupied by 3 digits
Thus, number of possible combinations to make a three digit number is
= 5 X 4 X 3
= 60
Therefore, total number of possible combinations to make a three digit number is 60
