About 72.5% of the Covid-19 vaccines distributed haven’t been used in California yet.

About 975,000 vaccines were used in California as of January 14, 2021. How many  vaccines did California have in the beginning?

1) 35 thousand

2) 2.7 million

3) 3.5 million

4) 27 million


Answer: 3

975,000 vaccines account for 27.5% of the total vaccines.

975,000/27.5 = X/100

X=975,000 x 100 / 27.5

X≅3,545,454
