For a certain event, 817 tickets were sold, for a total of $1919. if students paid $2 per ticket and nonstudents paid $3 per ticket, how many student tickets were sold?

532 student tickets were sold

Step-by-step explanation:

Let x be the no. of student's tickets sold

Let y be the no. of non student's tickets sold

We are given that 817 tickets were sold in total

So,  --1

Cost of 1 student's ticket = $2

So, Cost of x student's ticket = 2x

Cost of 1 non - student's ticket = $3

Cost of y non - student's ticket = 3y

We are given that  817 tickets were sold, for a total of $1919

So,  ---2

Solving 1 and 2

Substitute the value of y from 1 in 2

Substitute the value of x in 1

Hence 532 student tickets were sold

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

answer: $13,622.84
