Given problem;
Number of quarters in $40;
To solve this problem;
- <u>Convert the dollar value to cents</u>;
100cents = $1
In $40, we would have; 40 x 100 = 4000cents
So, divide 4000cents by 25 to obtain the number of quarters in that amount of dollars;
Number of quarters =
= 160
So there are 160 quarters in $40
First you must find what 9.5 percent of 78 is. To do so, put 9.5 percent as a decimal (.095). Next, take this (.095) decimal and multiply it by 78 (this gives you 9.5 percent of 78). You will end up with the number 7.41. Since 78 is being increased by 9.5%, add 7.41 to 78 to get the final answer of 85.41. Therefore, when 78 is increased by 9.5%, you get 85.41 as a result.
