Alex has x dollars per week available for lunch.She spends $3 on lunch every weekday. Write an algebraic expression to represent how much money she has left over at the end of the week.

Answer :

Answer:

The money Alex has left over at the end of the week is  ( x - $15).

Step-by-step explanation:

The total lunch allowance of a week = $x

The money spent on lunch every weekday = $3

Number of weekdays in a week = 5 days

Now, the total money spend in 5 weekdays  

=  5 x ( Money spend in 1 weekday)  = 5 ( $3) = $15

So, in  a week she spends $15 in a week.

Total amount Left  = Total Money - Money Spent  =  x - $15

Hence, the money Alex has left over at the end of the week is  ( x - $15).
