When Marcus was 6 years old, his dad planted a 7 foot maple tree. They can grow up to 2 feet per year. The tree is now 25 feet tall. How many years ago did his dad plant the tree

So we know that Marcus was 6 when they planted a 7 foot maple tree (how do they even "plant" that thing?), and it grows 2 feet per year.

So that means it grew 25-7 =  18 feet.

18 / 2 = 9.

So that means it grew 18 feet in 9 years.

That means that Marcus's dad planted the tree 9 years ago.

step-by-step explanation:

the total is 23.97. 0.25% is off so you have to subtracting 25% from 100% and you will get 75% if you convert it to decimal you will get 0.75. you have to find the original because the formula is % times original = total.so you have the total and the % so you just have to plug it in.

answer: since the question is talking about growth you have to use the growth formula which is inital amount (1 + growth)^time

step-by-step explanation:

the intial amount is 1200, the growth is 4.8, and the time is 7. plug those numbers into the equation, also i think you have to change 4.8 into a percent. but, i have forgotton how to do that. if this is a online class go on to the lesson.
