An author received $540 in royalties for sales of her book during its first month of publication. If 200 more copies had been sold during this time, she would have received $60 more in royalties. How many copies of the book sold during its first month of publication?
1,200
1,600
1,800
2,200
2,400
We know that 200 copies can generate 60$; we have to find how many books have generated 540$.
Simply divide 60/200 which is equal to 0.3. So this is the amount that is generated by one book. Now divided 540/0.3 which is equal to 1800.
Hence 1800 Books can generate 540$ reality.
