In a coin collecting book 30 nickels can fit in each of 8 pages and 36 dimes can fit on each of 6 pages. If the nickel book is 5/8 full and the dime book is 75% full, how much money is in the book?
Hint
Convert the fraction and percentage to a decimal.Answer
The answer is $23.70.This can be calculated through multiplication.
5/8 is equivalent to .625. The total amount of money that can be stored into the nickel section of the book is $12. 12x.625=7.5, or $7.50.
75% is equivalent to .75. The total amount of money that can be stored in the dime section of the book is $21.60. 21.6x.75=16.2, or $16.20.
If you add these numbers ($7.50 and $16.20) you end up with a sum of $23.70.
