17. A television costs $270.25 including 15% sales tax. How much of
the cost is tax?

The sales tax is $40,5375

Step-by-step explanation:

270.25 / 100 = 2,7025

2,7025 * 15 = 40,5375

Below in bold.

Step-by-step explanation:

The 15% is calculated on the cost before tax, $x.

So x + 0.15x = 270.25

1.15x = 270.25

x = 270.25/1.15

= $235.

So 270.25 - 235

= $35.25 was sales tax.

i dont know if you cant find a way its best to actually add all of them start from 105 tho

step-by-step explanation:

to determine the unit cost your would divide the total cost by the number sold.

7 bagels for $4.41       $4.41/7 = $.63 each at fresh side

5 bagels for $3.60         $3.60/5 = $.72 each at value mart
