Answer:
Total number of copies sold till date are 381522.
Step-by-step explanation:
It is given in the question the book sold 35100 copies in its first month of release and this number is 9.2% of the number of copies sold till date.
To find is how many copies have been sold.
Let the total number of copies sold be = A
Therefore 9.2% × A = 35100
A = 381521.74 ≅381522 copies
To find the original price before the increase, divide the new price by 1 + the percent of increase.
198 / 1.20 = 165
The original price was $165
Answer:
Part A
12 months a year means
%74.5 x 12 = $894
Part B
4 weeks in a month means
$74.5 ÷ 4 = $18.625
But rounded to the nearest penny. . .
$18.62
because in the thousandths place was a 5 and you round up when there is a 5 or above
Part C
We will go with 31 days in a month, but I will also do 30 for you
$74.5 ÷ 30 = $2.48333
But rounded to the nearest penny. . .
$2.48
because you round down when there is anything less than a 4
$74.5 ÷ 31 = $2.40322580645
But rounded to the nearest penny. . .
$2.40
because you round down when there is anything less than a 4
