Question 473267: not sure where to input the 66
1. The attendants at a parking lot park cars in temporary spaces before the cars are taken to permanent parking stalls. The number N of such permanent spaces needed is approximated by the function:
N(a) = 2.5 squareroot a
Where a is the average number of arrivals.
a) What is the number of spaces needed when the average number of
arrivals is 66? What is it when the average is 100?

a)

N%28a%29=2.5%2Asqrt%28a%29


N%2866%29=2.5%2Asqrt%2866%29


N%2866%29=2.5%2A8.12403840463597


N%2866%29=20.31009601159


Round up to get 21. So you'll need 21 spaces if the average number of arrivals is 66.

--------------------------


N%28a%29=2.5%2Asqrt%28a%29


N%28100%29=2.5%2Asqrt%28100%29


N%28100%29=2.5%2A10


N%28100%29=25


So you'll need 25 spaces if the average number of arrivals is 100.
