For monthly membership, the cost must be less than $325. We can set up an inequality:-

100 + 30x < 325 where x = number of months of membership

Solving -

30x < 325-100 = 225

x < 225 / 30

x < 7.5 months

The answer is 7 months.

Kate and Jean paint a house together in 6 days. If they work alone, Kate takes 5 fewer days than Jean would take to do the same

dsp73

Answer: $x^2-17x+30=0$

Step-by-step explanation:

Let x = Time taken (in days) by Jean to do the job.

Then, Time taken by Kate to do the job = x-5

Then, together they will take time (t) as

$\dfrac{1}{t}=\dfrac{1}{x}+\dfrac{1}{x-5}$

$=\dfrac{x-5+x}{x(x-5)}=\dfrac{2x-5}{x(x-5)}$ .

$\Rightarrow\ t=\dfrac{x(x-5)}{2x-5}$

Since it is given that Kate and Jean paint a house together in 6 days.

i.e.

$6=\dfrac{x(x-5)}{2x-5}\\\\\Rightarrow 6(2x-5)=x^2-5x\\\\\Rightarrow\ 12x-30=x^2-5x\\\\\Rightarrow\ x^2-5x-12x+30=0\\\\\Rightarrow\ x^2-17x+30=0$

So, the equation represents the time it takes Kate to paint the house by herself is $x^2-17x+30=0$ .
