Ashopper buys 3 notebooks for $5 each. the percent of sales tax 8%. how much is the total sale?

Hey!

Steps To Solve:

~Multiply

3 x 5 = $15 (costs for all 3 notebooks)

~Turn into decimal

8% = 0.08

~Multiply

15 x 0.08 = $1.20 (sales tax)

~Add

15 + 1.20 = $16.20 (total sale)

$16.20 is the total sale.

Hope This Helped! Good Luck!

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

i used to know how to do this in 7th but i forget easily
