Question

A book sold 31,600 copies in its first month of release, and this represents 7.7% of the total number of copies sold to date. How many copies have been sold to date?

Answer 1

To find the total number of copies sold to date, set up a proportion using the percentage of copies sold in the first month. Multiply the percentage by the total number of copies sold in the first month and divide by the percentage as a decimal to find the total number of copies sold to date. The total number of copies sold to date is 409,091 copies.

Step-by-step explanation:

To find the total number of copies sold to date, we can set up a proportion:

Total number of copies sold to date / Total number of copies sold in the first month = 100% / Percentage of copies sold in the first montH.

Plugging in the given values:

Total number of copies sold to date / 31,600 = 100% / 7.7%

Multiplying both sides of the equation by 31,600:

Total number of copies sold to date = (31,600 * 100%) / 7.7%

Converting the percentage to a decimal:

Total number of copies sold to date = (31,600 * 1) / 0.077

Total number of copies sold to date = 409,091 copies
