Answer:
k = 324
Step-by-step explanation:
Y varies inversely as x
Let k be the constant of variation
Y = k/ x
Y= 36 and x= 9
Substitute the value of Y and x
36 = k/9
Make k the subject of the formula
k= 36*9
k =324
Cost = (3,500) * (1.04)^years
Cost = (3,500) * (1.04)^4
<span><span><span>Cost = (3,500) * 1.16985856
</span>
</span>
</span>
<span><span>Cost = </span>4,094.50</span>
Simplified answer would be 60k^2+k
and you get that answer by combining like terms, Good Luck!
