Meryl needs to cut down 10.5 trees for every 5 cabins she builds. How many trees will she need to cut down if she builds 7 cabins?

14.7 trees

Step-by-step explanation:

First you need to find how many trees she cuts down to build one cabin. So you divide:

10.5/5=2.1

She cuts down 2.1 trees to make one cabin.

Next you multiply:

2.1*7=14.7

14.7 trees

Step-by-step explanation:

First you need to find how many trees she cuts down to build one cabin. So you divide:

10.5/5=2.1

She cuts down 2.1 trees to make one cabin.

Next you multiply:

2.1*7=14.7

6.3 trees.

Step-by-step explanation:

We have been given that Meryl needs to cut down 10.5 trees for every 5 cabins she builds.

Let us find the number of trees Meryl needs to cut down to build 1 cabin by dividing 10.5 by 5.

Now let us multiply 2.1 by 3 to find the number of trees Meryl needs to cut down to build 3 cabins.

Therefore, Meryl needs to cut down 6.3 trees, if she builds 3 cabins.

SI=(P*R*T)/100

P=2000

R=1.5

T=6

SI=(2000*1.5*6)/100

=(2000*9)/100

=180

Neil will earn interest of 180
