Question

a book sold 33,600 copies in its first month of release. suppose this represents 6.7% of the number of copies sold to date. how many copies have been sold to date? answer to the nearest whole number

Answer 1

We can start by setting up a proportion:

6.7% = 33,600/x

To solve for x, we can cross-multiply:

0.067x = 33,600

Dividing both sides by 0.067 gives:

x = 500,000

Therefore, approximately 500,000 copies have been sold to date.

Answer 2

First, 6.7 % can be written in decimal form as 0.067 (6.7 / 100 = 0.067).

Let's use the variable x to represent the number of copies sold to date.

Then we can write and solve the following equation to represent 6.7% of the total sold to date:

0.067 • x = 33600

You can solve this equation by dividing both sides of the equation by 0.067:

0.067 • x = 33600

0.067 0.067

x = 501493

To date, 500000 copies would have been sold rounded to the nearest whole.
