A nickel is worth 5 cents. So if he has 5 nickels extra. They are worth 25 cents. Subtract 0.25 from 4.35 and you get 4.10. Now all you have to do is divide 4.10 by 0.05, which is a nickel. The answer is "Mike thought he had 82 nickels"
$4.10, five nickels is eqivalent to 5 cents per nickel. therefore 5 centsx5 nickels=25 cents(the amount more than he thought was there). next you subract the amount extra from the amount total to get the answer
