Georgia Connections Academy is selling tickets to its Spring Fling. Adult tickets cost $4 and student tickets cost $2.50. The school makes $2,820. Write an equation that represents this situation to find the cost of all adult and student tickets sold. Use the variable s for student tickets and a for adult tickets sold.

Answers

Answer:

Step-by-step explanation:

We use a for Adult and s for Student.

Assuming this, you have to start by writing two equations from the information provided:

900 total tickets were sold

a+s=900 ------(i)

they made $2,820 and adult tickets cost $4 and kids tickets cost $2.50

2820=4a+2.5s ------(ii)

lets solve for a in the first equation:

a=900-s

we can plug this into the second equation and solve for s

2820=4(900-s)+2.5s

2820=3600-4s+2.5s

2820=3600-1.5s

-780=-1.5s

s=520

we can plug this into the first equation and solve for a:

a+520=900

a=380

Total adult ticket sold : 380

Total student ticket sold = 520

Cost of adult tickets = 380 * 4 = $1520

Cost of student tickets = 520 * 2.5 = $1300

Answer:

No, they are not in proportion

Step-by-step explanation:

As when we cross-multiply 2/3 and 7/10, we get 20 = 21

When we cross-multiply 1 and 3/5, we get 5 = 3

When we cross-multiply 4/3 and 1/2, we get 8 = 3

20=21 ≠ 5=3 ≠ 8=3

∴ Hence, they are not in proportion.

Suppose you are solving a real-world problem that contains fractions, mixed numbers, percents, and decimals. Why might it be helpful to convert all the values to one form? How would you determine which form to use?

Answers

It might be helpful to convert all the values to one form because:

1. You can't easily add or subtract values that are in a different form.

2. It is easier to visualize when working with greater than/less than problems.

______________________

I would determine which form to use based on the problem. For example, when dealing with dividing up slices of pie, it would be easiest for me to use fractions or mixed numbers, while in a problem involving how many blue buttons are in a bag of multicolored buttons it would be easiest for me to use percentages.
