1. Sketch a graph that represents the following situation. Be sure to label the graph appropriately.

A student with an internship for the summer borrowed money from his mom to purchase a new phone for $1200. The graph shows the amount the student owes his mom as he makes $100 payments once a week for 5 weeks.

2.

$400 is put into an account and it increases according to the equation A(t) = 400(1. 03)t Complete the following table of values using t : 0, 5,10, 15, 20 and create a graph of this situation using the table of values. Is the graph continuous or discrete? Answer: t A(t) o 400 5 463.71 '1 0 537.57 'I 5 623.1 9 20 722.45 Discrete since there are points to be plotted on a graph
