Mr. Barsotti received a gift card for the local coffee shop. He buys the same drink each day. The value on his card has decreased by $33.30 after
9 trips to the coffee shop. Determine how much each coffee costs him.

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.

lol   i know im kinda tired too

i like this question, it is unsual, are you sure it is sqrt and not squared?
