A 12
B 14
C 120
D 140

Answer 1

Answer:

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.
