A fitness center currently has 320 members. Monthly memberships fees are $45. The manager of the fitness center has determined t

erma4kov [3.2K]

Answer:

The required equation :

$y=(320-10x)(45+5x)=14400+1150x-50x^2$

Step-by-step explanation:

Given : A fitness center currently has 320 members. Monthly memberships fees are $45. The manager of the fitness center has determined that each time the membership increases by $5, approximately 10 members leave and go to a different gym.

To write : A equation that can be used to find the revenue of the fitness center in dollars,y, after x price increases of $5.

Solution :

Revenue is defined by the amount or price during specific period.

Let x be the number of months,

y be the revenue of the fitness center.

The number of members in the fitness center is 320 but after increasing $5 10 members leave.

So, the total member after increment in x months are $320-10x$

Monthly memberships fees are $45.

The manager of the fitness center has determined that each time the membership increases by $5.

The price of monthly membership after increment is $45+5x$

So, The equation which gave the revenue of the fitness center is

$y=(320-10x)(45+5x)$

$y=14400+1600x-450x-50x^2$

$y=14400+1150x-50x^2$

A bag contains 6 red marbles, 3 blue marbles and 8 green marbles. If three marbles are drawn out of the bag, what is the probabi

ale4655 [162]

This is a 4 step problem.

Find the probability of drawing a green marble the first time

8 green marbles ÷ 17 total marbles

Next, we find the probability of drawing a green marble the second time

7 green marbles ÷ 16 total marbles

Find the probability of drawing a green marble the third time

6 green marbles ÷ 15 total marbles

We take away one from the total marbles and green marbles each time because we are finding the probability that we draw a green marble all three times

Last step:

Multiply all the probabilities

$\frac{8}{17}$ × $\frac{7}{16}$ × $\frac{6}{15}$
