Mrs. johnson spent $611 buying lunch for 78 students. if all the lunches cost the same, about how much did she spend on each lunch?

The total amount Mrs Johnson spent on each student’s lunch is $7.83

To determine the amount spent on the each lunch, and since all the lunches cost the same, the total amount spent on the students’ lunch (611) will be divided by the total number of the students (78)

Therefore,

=

= 7.83

Hence, the total amount spent on each lunch is $7.83

The above expression is a mathematical number problem. And an order of operation i.e BODMAS was used to derive the solution.

BODMAS represent Bracket, Of, Division, Multiplication, Addition, Subtraction. The main mathematical tool that used to solve the provision is Division.
