A bag with quarters and nickels contains 87 coins. The total amount is $7.35. How many quarter and nickels are in the bag

72 nickels and 15 quarters

Step-by-step explanation:

72 times .05 = 3.6 or $3.60

15 times .25 = $3.75

Total = $7.35

.05 is representing the nickels and .25 is representing the quarters and if you take a calculator and do 87-72 you get 15 and you can set it up yourself to double check. But I wouldn't recommend doing it with pennies that's how I got confused so many times and you can also give yourself a similar problem if you want to make sure you know how to do it. Sorry if this was confusing.

for the points! : )

your answer is 228

step-by-step explanation:

add the top and bottom bases together, then divide them by 2, then multiply by the height.
