An investor puts $750 into an account. The account averages an annual growth rate of 8%. The investor adds no new money to the account. She decides she will keep the account until its value has at least tripled. Which inequality can be used to represent the number of years, t, it will take for the account to triple in value?

it would open into a square depending on the type of envelope i’m not sure about the second part

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.
