Question

A landscaper buys a tree that grows at a rate of 14 inches every 2 months. 

How much does it grow in 1 year?



A.) 24 in.


B.) 84 in.


C.) 42 in.


D.) 70 in.

Answer 1

First off,we need to find out how many 2 months is in a year. As a year has 12 months,we divide 12 by 2 to find out:

12÷2
=6

We can then proceed to find the answer, as the tree grows 14 inches each two months,in a year it will grow 14 inches 6 times.

We can then find the equation of the tree growth:

14×6
=84inches

Therefore the answer is B.84 inches.

Alternatively,in one equation:

(12÷2)×14
=6×14
=84inches

Hope it helps!

Answer 2

There are 6 "two-month periods" in a year, where the tree will grow 14 inches each period. Thus, the tree grows a total of:

`6 \cdot 14\, \textrm{in} = \boxed{84 \,\textrm{in}}`

The answer is B, 84 in.
