If Mike had a total of $4.35 in nickels and there were five more nickels than he thought, how many nickels did he originally believe he had?

The correct answer is: 82

To determine how many nickels Mike originally believed he had, we start by recognizing that the total amount of money he has, $4.35, is equivalent to 435 cents. Since nickels are worth 5 cents each, we can express the number of nickels he has in terms of cents. Let's denote the number of nickels Mike originally believed he had as $ x $. According to the problem, Mike actually has five more nickels than he believed, which would make it $ x + 5 $ nickels. The total value of the nickels can thus be represented as: \[ 5(x + 5) = 435 \] Now we simplify and solve that equation: 1. Distributing the 5: \[ 5x + 25 = 435 \] 2. Subtracting 25 from both sides: \[ 5x = 410 \] 3. Dividing both sides by 5: \[ x = 82 \] This calculation shows that Mike originally believed he had 82 nickels. The value of the total number of nickels he actually possesses (which is 82 + 5 = 87 nickels) indeed totals to
