27 coins of quarters (25¢) and nickels (5¢) total $3.95. How many nickels are there?

 4 nickels

Step-by-step explanation:

First you need to calculate how many cents there are in 27 quarters.  To do so, you need to multiply 27 by 25 because each quarter is worth 25 cents.  Then divide that answer by 100.  When multiplied the answer should be 675.  675 ÷ 100 = $6.75 which means because nickels equal 5 cents, you would need 4 nickels to make $3.95.

question is incomplete.

81 seats

step-by-step explanation:

if you multiply 0.65 times 125 then you get 81.5 seats. well since you can't have half of a seat you have to round down and get 81 seats in the no children zones. that leave 44 seats outside of the no children zone.
