Question 702561: The cost to produce 10 units of a product is $40 and the cost to produce 20 units is
$70. If cost (C) is linearly related to the number of items, (q), produced, find the linear equation that represents this relationship, then use this equation to determine the cost of producing 17 items. would the formula and equation below be correct?
(difference of c)/(difference of q).
(70-40)/(20-10)=3,
Applying the same slope or ratio to 17,
(C-40)/(17-10)=3,
C-40=3(17-10),
C = 21 + 40 = 61

A painter is paid 9 dollars per hour and can paint 8 m^2 with a roller in this time. Renting a spray gun costs 5 dollars for each hour of use, and the painter can paint 20 m^2 per hour with the spray gun. It takes 1/2 an hour for the painter to clean up after using the roller, but 1 hour using the spray gun. You must pay the painter for her time and you must also pay for renting the spray gun for the total amount of time (including clean up) the spray gun was needed. How much money do you save by using the spray gun on a paint job that involves painting 40 m^2.
