A scale factor is a number which scales, or multiplies, some quantity. In the equation y = Cx, C is the scale factor for x. C is also the coefficient of x, and may be called the constant of proportionality of y to x.
The total cost for one can is: $25.41.
__________________________________________________
Let us assume that we want to know the total cost of ONE CAN.
_____________________________________________
To calculate our answer:
_______________________________
$ 23.97 + [ (6/100) * 23.97)] = Our answer, in dollars.
__________________________________________
Note: "6%" = 6/100 = 0.06
_______________________
Rewrite as:
____________
$ 23.97 + [ (6/100) * 23.97)] = our answer, in dollars;
_____________________________________________
$ 23.97 + (0.06 * 23.97)
= $ 23.97 + 1.4382
= $ 25.4082 ; Round to decimal places, to get:

Answer:
14. m = 7/8
15 x =63
16. y= 21/2
Step-by-step explanation:
14. 7 16
---- = --------
m 2
using cross products
7 * 2 = 16 * m
14 = 16m
divide by 16
14/16 = m
simplifiy
7/8 =m
14. x 14
---- = --------
18 4
using cross products
4 * x = 18 * 14
4x = 252
divide by 4
4x/4 = 252/4
x = 63
15. 30 y
---- = --------
20 7
using cross products
30*7 = 20 y
210 = 20 y
divide by 20
210/20 =y
21/2 = y
These problems are what is known as changing a mixed fraction to an improper fraction. Lets start with 5 1/8.
What we want to do is take the big number on the side and add it to the top of the fraction in a special way to make it an improper fraction. (An improper fraction means a fraction with a bigger top than bottom).
To add 5 to 1/8, we have to multiply 5 by 8 and then add it. 5 times 8 is 40 so if we add that to the top we know that the improper fraction we are looking for is 41/8.
We can do the same thing for 3 4/12, multiply 3 by 12 and add it to the top of the fraction. 3 times 12 is 36, add that to the top to get 40/12.
See if you can do 1 6/12 and comment with an answer, if you get it wrong I will keep helping you till we get this down!
