Explanation:
To find the total cost of 8 pieces of bubble gum that are $0.20 each, you can multiply the cost of one piece ($0.20) by the number of pieces (8).
$0.20 * 8 = $1.60
To represent this on a number line, you start at 0.2 (the cost of one piece of gum) and move 8 hash marks to the right. Each hash mark represents an addition of $0.20. So, when you move 8 hash marks, you end up at $1.60, which is the total cost of the 8 pieces of gum.
