Island Nautical Supply Co. is having a sale on kayaks, 20% off of the regular price. You found a super nice one that is regularly priced at $259.00. How much will it cost after the sale? (Show Work.)

A: $51.80
B: $239.00
C: $207.20

C

Step-by-step explanation:

Multiply 259 by .2 then subtract that number (51.8) from 259

c

Step-by-step explanation:

you will divide 259.00 by 20%

1.4

2.3

step-by-step explanation:

the formula for the constant of variation is

y= kx

divide each side by x

y/x =kx/x

y/x =k

we know a and y

1.   y/x = k

4/1 =4

check the other values to make sure they are the same

8/2 = 4   12/3 =4   and 16/4 =4  

the constant of variation is 4

2.   y/x = k

3/1 =3

check the other values to make sure they are the same

6/2 = 3   9/3 =3   and 12/4 =3  

the constant of variation is 3
