Question

Write an equation for the number of dollars, d, you spend on b boxes.

Yesterday, you purchased 2 boxes. Today you purchase 5 boxes.
Place points on the graph to show your purchases yesterday and today.

Answer 1

d = 6b

Explanation:

The number of dollars will be 6 times the number of boxes you buy.

When you buy 2 boxes, it costs 6 * 2 = $12, so one point should go at (2, 12).

When you buy 5 boxes, it costs 6 * 5 = $30, so one point should go at (5, 30)
