The regular price is 3.18.
50% off half the price, so you can either divide the regular price by 2 or multiply it by 0.50
3.18 / 2 = 1.59 ( 3.18 *0.50 = 1.59)
so the sale price is 1.59
now subtract the sale price from $5 to find the amount of change they got back:
5.00 - 1.59 = $3.14 change back

the answer is 40 hope this helps you
You have not provided a function, however, normally when the instructions say to use graphs, you just need to graph it in your calculator and then take a look at it to see what the limit will be at the requested x value. Remember to write your asymptote as a linear equation once you identify it from the graph.
