Answer:
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.
