Show your work.

$17.69

Step-by-step explanation:

Amount had = $15

Items to be purchased = 2 gallons of fruit juice, 3 bags of chips, and a box of cupcakes.

First gallon of juice = $3.50

Second gallon = 0.5 * 3.50 = $1.75

3 Bags of chips = $2.65 + $5 = $7.65

A box of cupcake = $4.79

Total cost before tax = $(3.50 + 1.75 + 7.65 + 4.79)

= $17.69

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.
