The first visit, Mr. Juniper worked 4 hours and charged $245. The second time he worked 2.5 hours and charged $185. Let x be the number of hours Mr. juniper works in a single visit, and let y be the total amount, in dollars, that he charged for the visit. a. [4 pts] Create the equation that relates the total cost to the time worked. Note: This will be a linear relationship, so start by finding the slope of the line based on the given information. Express the final equation in y = mx + b form. b. [2 pts] How much would Mr. Juniper charge for 3.5 hours of work? Include units
