The sales tax on a coat Mary bought was 6%. The coat cost her $95.50, how much tax did she pay for the tax? What is the total cost of the coat including tax?

$5.73 and $101.23

Step-by-step explanation:

Given that

The sales tax rate is 6%

The coat cost $95.50

We need to find out the tax payment

And, the total cost including the tax

So,

The tax payment is

= $95.50 × 6%

= $5.73

And, the total cost of the coat including the tax is

= $95.50 + $5.73

= $101.23

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional
