Q. Mason has some nickels and some dimes. He has a minimum of 1515 coins worth at most $1 \$ 1 combined. If Mason has 33 dimes, determine the maximum number of nickels that he could have.\newlineAnswer:
  1. Calculate Dime Value: First, let's determine the value of the dimes Mason has.\newlineSince each dime is worth $0.10\$0.10, 33 dimes are worth 3×$0.103 \times \$0.10.\newlineCalculation: 3×$0.10=$0.303 \times \$0.10 = \$0.30
  2. Calculate Remaining Amount: Now, let's calculate the remaining amount that can be allocated to nickels. Mason has at most $1\$1, and he already has $0.30\$0.30 in dimes. Calculation: $1.00$0.30=$0.70\$1.00 - \$0.30 = \$0.70
  3. Calculate Maximum Nickels: Each nickel is worth \$\(0\).\(05\). To find the maximum number of nickels Mason can have, we divide the remaining amount by the value of one nickel.\(\newline\)Calculation: \$\(0\).\(70\) \div \$\(0\).\(05\) = \(14\) nickels
  4. Ensure Total Coins: We must ensure that the total number of coins is at least \(15\). Mason already has \(3\) dimes, so adding \(14\) nickels would give him a total of \(17\) coins.\(\newline\)Calculation: \(3\) dimes \(+\) \(14\) nickels \(=\) \(17\) coins
  5. Final Conclusion: Since \(17\) coins are more than the minimum of \(15\) coins required, Mason can indeed have \(14\) nickels along with his \(3\) dimes.
