The environmental club has saved 375 pounds of cans and promises to collect 12 pounds of cans each week. They will use the profits from the sales of the cans to buy additional recycling bins.

(Express all answers rounded correctly to the nearest tenth!)

(i) If we construct a linear model to predict the number of pounds of cans the club will have at the end of a given week, what is the slope,m, for this model.

(ii) If we construct a linear model to predict the number of pounds of cans the club will have at the end of a given week, what is the starting value,b, for this model.

(iii) Use a linear model for their collection program to predict how many pounds of cans the club will have by week 33.
