You create a graph to represent the number of people who join the Equestrian Club during a 7 day period. Would this be a continuous or discrete graph?

• The graph will be continuous because there can be any number of people signing up each day.

• The graph will be discrete because there is no such thing as a partial person to sign up and the booth is set up once each day for sign ups.

• The graph will be discrete because some day the number of available people to sign up for the club will run out.

Diep buys a loaf of bread 65 centimeters long. For lunch every afternoon, he cuts 15 centimeters of bread for his sandwich. Diep wants to determine the length of the loaf of bread, l, after d days. What is the equation of the scenario? Is the graph of the equation continuous or discrete?

• l = 65 – 15d; discrete

• l = 65 – 15d; continuous

• 65 = l – 15d; discrete

• 65 = l – 15d; continuous

Sonji has $5.25 in nickels and dimes.The coin value can be modeled by the equation, 

 $0.10d+0.05n=5.25$ 

where d represents the number of dimes and n represents the number of nickels. If Sonji has 21 dimes, how many nickels does she have?

Manny has 48 feet of wood. He wants to use all of it to create a border around a garden. The equation 

 $2l\ +\ 2w\ =\ 48$  

can be used to find the length and width of the garden, where l is the length and w is the width of the garden. If Manny makes the garden 15 feet long, how wide should the garden be?
