Cost function=fixed cost + variable cost
=400+(something)
okay let's think
we can only sell q shirts per week
and each shirt cost us 4 dollars
so i think the Cost function
=400+4q
=400+4(-40x+800)
=400-160x+3200
=-160x+3600
but i'm not sure of the this terminology
I agree with Josie, because it would be easier since the other three numbers are decimals. If you prefer fractions, then change the three decimals to mixed numbers.
Answer:
Step-by-step explanation:
27x + 12y = -216
8x - 12y = -64
35x = -280
x= -8
2(-8) - 3y = -16
-16 - 3y = -16
-3y = 0
y = 0
(-8, 0)
