// Question 1a

// Question 1b

// 40


// Question 1c

// 30.333333333333332


// Question 2a

// Question 6

// 23


// Question 7 need help!!!!!!!!Write a function that takes two parameters, 
// word and n, as arguments and returns the word concatenated to itself n number of times. 
// (i.e. if I pass in ‘Hello’ and 3, I would expect the function to return ‘HelloHelloHello’).

function wordConCat(word, n){

// Question 8
function fullName(firstName, lastName){

// Avery Doyle

// Question 9

// Question 11

// 47.75
// 7
// true


// Question 12

// true

// Question 13 Create a function of your own that solves a problem. 
// In comments, write what the function does and why you created it.
