A book sold 34,600 copies in its first month of release. Suppose this represents 8.6% of the number of copies sold to date. How many copies have been sold to date?

Respuesta :

Answer:402325.6

Step-by-step explanation:

let a be the total sales till date

8.6% of a=34600

8.6/100 x a=34600

0.086 x a=34600

divide both sides by 0.086

(0.086 x a)/0.086=34600/0.086

a=402325.6

Step-by-step explanation:

let the total =y

8.6% of y=34,600

8.6/100*y=34,600

86/1000*y= 34,600

cross multiply

86y=34,600*1000

y=34,600,000/86

y=402,325.581

to the nearest unit

y=402,326 sold.
