so you have 2 ordered pairs of the type
(brownies, cost) , (2000,1500) , (4000, 2000)
slope = (2000-1500)/(4000-2000) = 500/2000 = 1/4
using the 2nd point, ...
cost - 2000 = (1/4)(brownies - 4000)
4 C - 8000 = B - 4000
B - 4C = -4000
(checking if 1st point satisfies ...
LS = 2000 - 4(1500)
= -4000 = RS, YUPP )
variations:
B = 4C - 4000
-4C = -B - 4000
C = (1/4)B + 1000
you produce 2000 brownies in a month you have a monthly cost of $1500. when you produce 4000 brownies your monthly cost is $2000. assume that each brownie has a constant amount answer the folloing questons : a. write down a linar equation that gives the cost amout , the products, and the dollar amount
