Jose has a coin collection. He keeps 9 of the coins , which is only 5% of his entire collection in a box. what is the total of coins in Jose’s coin collection? I really need help with this question!

A. 14

B. 18

C. 160

D. 180

Jose's total collection is: 180

Hence, option D is correct.

Step-by-step explanation:

Let x be Jose's total collection.

Given that Jose keeps 9 of the coins, which is only 5% of his entire collection in a box.

It means,

5% of x = 9

5/100 × x = 9

0.05 × x = 9

divide both sides by 0.05

0.05x/0.05 = 9/0.05

x = 180

Therefore, Jose's total collection is: 180

Hence, option D is correct.
