For a school drama performance, student tickets cost $5 each and adult tickets cost $10 each. the sellers collected $3,570 from 512 tickets sold. if c is the number of student tickets sold, which equation can be used to find the amount of tickets sold of each type?

The system of equations is equal to

The number of adult tickets sold is

The number of student tickets sold is

Step-by-step explanation:

Let

c------>  the number of student tickets sold

a----->  the number of adult tickets sold

we know that

-----> equation A

-----> equation B

Using a graphing tool

The solution of the system of equations is the intersection point both graphs

see the attached figure

The intersection point is

therefore

the solution is

the number of adult tickets sold is

the number of student tickets sold is

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt

c
