Kate has a coin collection, She keeps 7 of the coins ln a box. Which is only 5% of her entire collection, What is the total number of coins in Kate's coin collection?

A 12

B 14

C 120

D 140

D

Step-by-step explanation:

This basically means "7 is 5% of what number (total) ".

We can directly translate this into algebra:

Note: "is" means "equal" AND "of" means "multiplication". Also, let the total be n

Let's write the equation.

"7 is 5% of what number (total) "

7 = 5% * n

5% means 0.05, so:

7 = 0.05 * n

n = 7/0.05 = 140

Total number of coins is 140

Option D is right.
