Answer:
$108
Step-by-step explanation:
36 times 3 equals 108
Given:
To rent a certain meeting room, a college charges a reservation fee of $39 and an additional fee of $8.40 per hour.
Let the number of hours = t and the total fee = F
So,
The chemistry club wants to spend less than $72.60 on renting the meeting room.
So, substitute with F = 72.6 and solve for t
so, the answer will be time should not exceed 4 hours
t = 15 + x and t = 5 + 2x represents the system of equations for this real world situation
<em><u>Solution:</u></em>
<em><u>Workout Gym has a sign up fee of $15 and charges $1 per day for membership</u></em>
Therefore,
Sign up fee = $ 15
Charge per day = $ 1
Let "x" be the number of days charged for membership
Let "t" be the total charge for membership
<em><u>Thus, we frame a equation as:</u></em>
Total fee = sign up fee + charge per day (number of days)
Total fee = 15 + 1(x)
t = 15 + x ------- eqn 1
<em><u>Healthy Gym has a $5 sign up fee and charges a $2 daily fee</u></em>
Sign up fee = $ 5
Charge per day = $ 2
Let "x" be the number of days charged for membership
Let "t" be the total charge for membership
<em><u>Thus, we frame a equation as:</u></em>
Total fee = sign up fee + charge per day (number of days)
t = 5 + 2(x)
t = 5 + 2x ------- eqn 2
Thus eqn 1 and eqn 2 represent the system of equations for this situation

1) x - number of nickels
2x - 1 - number of dimes
y - number of quarters
Altogether number of coins: x+2x-1+y =25, or 3x - 1 +y =25, 3x+y=26
2) 5x + 10(2x - 1) +25y = 490 (cents)
5x + 20x - 10 +25y = 490
25x +25y=500
x+y=20
3) Now, we need to solve a system of equations.
3x+y=26
x+y=20 → y=20 - x
3x+y=26 → 3x + 20 - x =26 → 2x = 6 → x= 3 (nickels)
y=20 - x → y =20 - 3 = 17 (quarters)
2x - 1 = 2*3 - 1 = 5 (dimes)
So, we have 3 (nickels), 17 (quarters), 5 (dimes).
