0.765 (100) + .06 (.0765 x 100)
76.5 + .06 (76.5)
76.5 + 4.59 = 81.09 Chris will pay $81.09
A better way ( if you don't care to know the tax just the bottom line of what it will cost) would be to do:
0.765x x 1.06 = 76.5 x 1.06 = $81.09 too.
Why the 1 in front of the .06? The one includes the price of the coat so you don't have to add the tax on after.
Think about it like this. When you buy something you pay (even with an employee
discount) for all of it (100%) + the tax (in this case, it's 6%) So you pay 106% of the cost of the item. 106% = 1.06
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
Answer: The nearest tenth would be 150.
Step-by-step explanation:
To round a number to the nearest tenth , look at the next place value to the right (the hundredths).
Remember y=mx+b
Since y=2 that means it is a horizontal line at 2 on the y axis which means it does not have a slope. The slope would be zero.
Rhombuses have acute and obtuse angles, so if it gives one just subtract it from 180
