A book sold 32,600 copies in its first month of release suppose this represents 8.2% of the number of copies sold to date how many copies have been sold to date round your answer to the nearest whole number

397,561 copies have been sold to date

Step-by-step explanation:

If 32,600 copies represent 8.2% of the whole

Let's assume the whole is Y

Therefore 8.2% of Y = 32,600 copies

Let's make Y the subject of formula by dividing both sides of the equation by 8.2%

(8.2% x Y) divided by 8.2% = 32,600 divided by 8.2%

Y = 32,600 / 8.2% = 397,561

step-by-step explanation:

to find if any function is an inverse of the other, put the first equation in as x in the next one. then simplify and solve. if at the end you get the statement y = x, then it is an inverse. if you get anything else, it is not.
