Write a statement that assigns numCoins with numNickels $+$ numDimes. Ex: $5$ nickels and $6$ dimes results in $11$ coins.

Note: Our autograder automatically runs your program several times, trying different test values each time to ensure your program works for any values. This program is tested twice, first with numNickels $=5$ and numDimes $=6,$ and then with numNickels $=9$ and numDimes $=0.$
