Aclass is going on a field trip to see a movie. each ticket is $7.00. the number of students, n, who will receive a $7.00 ticket is proportional to the total cost, c, of all the tickets. which equation could be used to find the total cost of all the tickets?

step-by-step explanation:

i hope this : )

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
