Does the equation 7c+8p=29.60 help us solve the original system? If you think so, explain how it helps. If you don't think so, explain why not and what would help us solve the system.

Graph the line that represents a proportional relationship between d and t with the property that an increase of 33 units in t corresponds to an increase of 44 units in d. what is the unit rate of change of dd with respect to t? (that is, a change of 11 unit in t will correspond to a change of how many units in d? )
