Your first line calculation is already true but reversed. The demand will decrease (that mean the formula would be minus) by 20 gallons for every $0.4 price increase, which means 50 gallons/$. To find the formula you need to insert one sample of either the first equation (65gallon and $3.1) or 2nd equation (45 gallons and $3.5). The formula for demand should be:
q= C - 50p
65 gallon= C- 3.1 * 50
C= 65 gallon + 155 gallon= 220 gallon
The formula would be:
q= 220- 50p
So the second question can be solved by putting 0 on the Q. It would be:
q= 220- 50p
0=220-50p
50p=220
p= $4.4

Answer:
Step-by-step explanation:
Figure consists of three parts; one Triangle , one rectangle and a square.
<u>Triangle: </u>
Base = b = 13+9 = 22 cm
height = 16 cm
<u>Rectangle 1: </u>
length = 14 cm
Width = 4 cm
Area of R1 = length * width = 14 * 4 = 56 cm²
<u>Area of Square R2:</u>
side = 8 cm
Area of square = side * side = 8 * 8 = 64 cm²
Area of shaded region = 176 + 56 + 64 = 296 cm²
I believe it would be $40
