Hello...


Tony and his three friends live in Albuquerque, New Mexico, but they all attend college in Boston, Massachusetts. Because they want to have a car at school this year, they are planning to drive Tony's car from Albuquerque to Boston at the beginning of the school year. Although they'll each pay for their own food during the road trip, the friends plan to split the costs for gas and hotels evenly between the four of them.

Estimate the total cost that each friend will have to pay for gas and hotels. Explain how you got your answer. Here are some figures that may help you out:

•Tony's car can travel 28 miles for each gallon of gas.

•The average fuel cost at the time of their trip is $3 per gallon.

•They plan to drive about 650 miles each day.

•They estimate the average cost of a hotel each night is $85.

•They will drive approximately 2,240 miles to get from Albuquerque to Boston.


Solution:

Cost of Gas:

2240 / 28 x 3 = $240

Cost of Lodging:

85 x floor2240 / 650 = $255

Cost of both: $240 +255 = $495.

The cost for a 1/4 share is $495/4 = $123.75.

A system of equations is shown.<br><br> 0.6d+0.05e=-4.5<br> -0.12d+0.3e=2.76 <br><br> d=<br> e=
Drupady [299]
I would multiply to get rid of the decimals and work with whole numbers.
Since we have numbers that are "hundredths", we would need to multiply every number by 100.
60d + 5e = -450
-12d + 30e = 276 Now that the decimals are gone, if we multiply the second equation by 5 the "d's" will cancel.
60d + 5e = -450
-60d + 150e = 1380
155e = 930
e = 6
Now plug 6 back in for e and solve for d.
60d + 5(6) = -450
60d + 30 = -450
60d = -480
d = -8
(-8, 6)
If you'd rather work it with decimals just let me know.

1500 concert tickets were sold $25 for covered pavilion seats and $15 for lawn seats total amount made $28,500
trasher [3.6K]

Question is Incomplete, Complete question is given below.

One evening 1500 concert tickets were sold for the Jazz Fest. Tickets cost $25 for covered pavilion seats and $15 for lawn seat. Total receipts were $28,500. How many of each type of ticket were sold?

Answer:

Number of Pavilion seat is 600 and number of lawn seats is 900.

Step-by-step explanation:

Given:

Total Number of ticket sold = 1500

Let number of Pavilion seat be x.

Let number of lawn seats be y.

hence the equation can be framed as;

x+y=1500 \ \ \ \ equation \ 1

Also Given

Total Amount made = $28,500

Cost of pavilion seat = $25

Cost of lawn seat = $15

Total Amount made is equal to Cost of pavilion seat multiplied by number of Pavilion seat plus Cost of lawn seat multiplied by number of lawn seats.

25x+15y = 28500

Dividing by 5 on both side we get;

5x+3y= 5700 \ \ \ \ equation \ 2

Now Multiplying equation by 3 we get;

3(x+y)=1500\times3\\3x+3y = 4500 \ \ \ \ equation \ 3

Now Subtracting equation 3 from 2 we get;

(5x+3y)-(3x+3y)=5700-4500\\5x+3y-3x-3y=1200\\2x=1200\\x=\frac{1200}{2}=600

Substituting the value of x in equation 1 we get;

x+y=1500\\600+y=1500\\y=1500-600\\y=900

Hence Number of Pavilion seat is 600 and number of lawn seats is 900.
