The correct answer is 2/3.
For this case we have the following equations:
y = 60x + 40
y = 50x + 80
Equaling both equations we have:
60x + 40 = 50x + 80
From here, we clear the value of x:
60x - 50x = 80 - 40
10x = 40
x = 40/10
x = 4 weeks
Substituting x = 4 in any of the equations we have:
y = 60 (4) + 40
y = 240 + 40
y = 280 $
Answer:
$ 280 4 weeks
C. -5.4 -17.6+12.2= -5.4 because -17.6 goes first in the calculator but also its a negative
Area of shaded region = 2(4*4)=2*16=32 in squared
