Question

Test Prep Alix 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 1

Answer:

The algebraic expression representing Money leftover at the end of the week is  $x-21\ Dollars$.

Step-by-step explanation:

Given:

Total Money Alix has per week  = 'x' Dollars

Money spent on each week days = $3

Number of days in week  = 7

Now we need to find the money left over at the end of the week.

Money left over at the end of the week can be calculated by Subtracting Money spent on each week days multiplied my number of day in week with Total money she has.

Framing in equation form we get;

Money left over at the end of week = $x-3\times7=x-21\ Dollars$

Hence The algebraic expression representing Money leftover at the end of the week is  $x-21\ Dollars$.
