Michelle bought a new calculator for math class. It cost $17.25. The tax rate is 5.50%. Calculate the tax and the total cost for the
calculator,

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

16.9 times 2.85

sorry i just need to anwers this to get points

step-by-step explanation:

you just switch the numbers basically so it would be 3/17
