The cost of a company picnic varies directly as the number of employees attending the picnic. if a company picnic costs $487.50 for 30 employees, how much does a company picnic cost for 80 employees? answer asap

The company picnic cost $ 1300 for 80 employees

Solution:

Given that cost of a company picnic varies directly as the number of employees attending the picnic

Let "c" be the company picnic cost

Let "n" be the number of employees attending the picnic

Therefore,

Where "k" is the constant of proportionality

c = kn ---------- eqn 1

Given that company picnic costs $487.50 for 30 employees

Therefore substitute c = 487.50 and n = 30

How much does a company picnic cost for 80 employees?

Substitute n = 80 and k = 16.25 in eqn 1

Thus $ 1300 is the cost for 80 employees

  answer:

  write 548 as 500 + 40 + 8. multiply each addend by 5. then add the three products to get 2,740.
