Answer:
273 square feet
Step-by-step explanation:
According to the scenario, computation of the given data are as follows,
Total ceiling area = 14ft × 20ft = 280 square feet
Diameter of circular light fixture = 3 feet
Radius of circular light fixture = 1.5 feet
So, Area of circular light fixture = π
= 
= 3.14 × 2.25
= 7.065 or 7 square feet
So, area for painting = Total ceiling area - Area of circular light fixture
= 280 - 7
= 273 square feet

Answer: the resale value would be $791 after 4 years
Step-by-step explanation:
We would apply the formula for exponential decay which is expressed as
y = b(1 - r)^x
Where
y represents the value of the laptop computer after x years.
x represents the number of years.
b represents the initial value of the laptop computer.
r represents rate of decay.
From the information given,
P = $2500
x = 4
r = 25% = 25/100 = 0.25
Therefore,
y = 2500(1 - 0.25)^4
y = 2500(0.75)^4
y = $791
The meals for all 9 cost 9x5 = $45
225-45= $180 which represent the entrance fees for all 9.
We divide that to 9 and we get the entrance fee per student!
180/9 = $20 / fee per student!
