Bob pays his daughter Jen a monthly allowance. He links the amount of the allowance to Jen's online activities. The more hours Jen spends on unproductive online resources, the less money she receives in her allowance. Bob gives $620 per month to Jen if she spends zero hours online. If Jen spends more than 0 hours but less than 120 hours, Bob deducts $2.5 per hour from $620. If Jen spends more than or equal to 120 hours, Bob gives $660 rather than $620 but deducts $3 per hour from $660. a) Write the function A (h) that relates online hours (h) to Jen's allowance. Show your work on paper. b) Graph the function A (h) by identifying intercepts on horizontal and vertical axes, coordinates of any holes, and breaks on the graph while h is on the horizontal axis. Show your work on paper. c) Identify at which point(s) the function A (h) is discontinuous by explicitly stating the right and left-hand limits of the function and the value of the function at the discontinuity. Show your work on paper. d) How much should Bob deduct per hour from $660 in order to remove the discontinuity
