Liam had $250. Then, he and his classmates bought a present for their teacher, evenly splitting the $120 among the e of them. How much money does Liam have left? Write your answer as an expression.

Answers

Answer:

$250-(120)/(e)$

Step-by-step explanation:

We have been given that Liam and his classmates bought a present for their teacher, evenly splitting the $120 among the 'e' of them.

This means that number of all students is 'e'. To find the cost of present for each student, we will divide 120 by e.

$\text{Cost of present for each student}=(120)/(e)$

Since Liam had $250, so we need to subtract $(120)/(e)$ from 250 to get amount Liam has left:

$\text{Amount Liam has left}=250-(120)/(e)$

Therefore, our required expression would be $250-(120)/(e)$ .

Liam Splits $40 With The 3 Of Them Out Of $120 And Liam Has 130 Because 250-120=130
