Answer
given,
opera house ticket = $50
attendance = 4000 persons
now,
opera house ticket = $52
attendance = 3800 person
assuming these are the points on the demand curve
(x, p) = (4000,50) and (x,p) = (3800,52)
using point slope formula
R(x) = x . p
at 
x = 4500
hence at x =4500 the revenue is maximum
for maximum revenue ticket price will be
p = $45
Slope: 7 given point: (1,8)
y = 7x + b step 1 - plug in the slope in the formula
8 = 7(1) + b step 2 - plug in the given point
8 = 7 + b step 3 - simplify the expression
b = 1 step 4 - solve for b
y = 7x + 1 step 5 - plug in b
formula: y = 7x + 1
13.5 * 12.2 = 164.7 i think that's the answer
Answer:
d = 22g/ 3 cm3
Step-by-step explanation:
Density = mass/ volume
d = 66g/ 9 cm3
d= 22g/3cm3
