Answer:
Step-by-step explanation:
Below is an attachment containing the solution to the question.
The company picnic cost $ 1300 for 80 employees
<em><u>Solution:</u></em>
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
<em><u>Given that company picnic costs $487.50 for 30 employees</u></em>
Therefore substitute c = 487.50 and n = 30

<em><u>How much does a company picnic cost for 80 employees?</u></em>
Substitute n = 80 and k = 16.25 in eqn 1

Thus $ 1300 is the cost for 80 employees
Answer:
The answer to the question provided is 1.
Answer:
x=-4
y=1
Step-by-step explanation:
For the given system of equations,
2.5x-3y=-13.....eqn(1)
3.25x-y=-14.....eqn(2)
We first make y the subject of eqn (2)
This implies that,
y=3.25x+14.....eqn(3)
We substitute eqn (3) into eqn (1)
2.5x-3(3.25x+14)=-13
2.5x-9.75x-42=-13
-42+13=9.75x-2.5x
-29=7.25x
Dividing through by 7.25, we obtain
x=-4
We now put the value of x into eqn (2)
3.25(-4)-y=-14
This implies that,
-13+14=y
y=1
