Consider the question. Jack and Jill shared the cost of renting a cottage that costs $5 an hour. If they rented it for eight hours, how much did each friend pay?
What is the step-by-step reasoning process to arrive at the answer: 20?
The total cost of renting the cottage for 8 hours is $5 x 8 = $40. So, each friend pay $40 / 2 = $20 each.
