Answer:
7 Quarters and 3 dimes
Step-by-step explanation:
You have to find how many quarters (0.25) and dimes (0.10) are in $2.05. There are 7 quarters, which will add up to $1.75. You can't have 8 quarters because then you would have 2 dollars, and there wouldn't be enough for a dime, there would only by 5 cents left, or a nickle. Then, you find out how many nickels you need, which is 3.
.10x3=.30. 1.75+0.3=2.05.

Answer:
total pages = 20
Step-by-step explanation:
60% of an unknown number is 12
Let the unknown number (total pages) be x.
60/100 of x = 12
60/100 * x = 12
3/5 x = 12
x = 12 * 5/3
x = 20
Answer: $41.24
Step-by-step explanation: In order to figure out how much she is away from 500 we need to first subtract the 65.99.
524.75 - 65.99 = 458.76
Then find the difference from 500 by subtracting again.
500 - 458.76 = 41.24
41.24 is the amount she needs to deposit in order to avoid a fee.
