The sales tax is $

The sales tax is 2.8 and the total cost is 72.8.

Step-by-step explanation:

4% = 0.04

70.00 × 0.04 = 2.8

70 + 2.8 = 72.8

Tax is $2.80

Step-by-step explanation:

When you multiply $70 by 0.04 (4% in decimal form), that is the answer you get, which tells you how much the sales tax is.

proportions are fractions that equal to each other. so if two fractions are the same, they are proportional.

let's check the answers to see if they are proportional.

question a is not proportional because you can't turn 1.5/3 to 3/9. if you try to multiply 1.5/3 by 2 or 3, you wont get 3/9. it's impossible to make the fractions the same.

question b is not proportional because you can't turn 22/33 to 4/6. 33 can't go into 6.

question c is proportional because when you multiply 2 and 3 by 71, you would get 142/213, and those fractions equal to each other

question d is proportional because when you divide 14 and 7 by 2, you would end up with 7/3.5, and those fractions equal to each other.
