For each of the following proportions, write a corresponding word problem. Make sure to include an unknown variable and to define the units. (Hint: Since you are asked to include a variable, you will leave one of the components of each proportion out so that I can solve for it when I read your word problems). 1. $10 2 tickets = $30 6 tickets inch 1 mile = 1 inch 4 miles 2. 1 salesperson 12 salespeople 3. 20 employees 240 employees
