If zöe orders a book from store y, how much tax will she pay? comparison of online bookstores store x store y cost of book $17.00 $18.00 tax rate 6% 8% shipping 10% of cost before tax free $1.44 $2.25 $12.25 $14.40

$1.44

Step-by-step explanation:

Given :

Comparison of Online Bookstores

                            Store X                                    Store Y                                                                                                              

Cost of book        $17.00                                    $18.00  

Tax Rate                6% =0.06                             8%=0.08                                                      

 Solution:

Cost of book at store Y = $18

Tax rate = 8%=0.08                                                                  

Tax  Zöe  will pay is she orders from Store Y = tax rate * cost = 0.08*18 =1.44

Hence she will pay $1.44 tax if she orders a book from Store Y

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

2/3x + 7 = 29

step-by-step explanation:

two thirds = 2/3

plus a number = x

at least 29 = 29

there for you should get 2/3x + 7 = 29
