Question

Twenty-five students go to lunch. Pizza costs $3 and sandwiches cost $2. Twelve students buy pizza. What is the total amount of money spent on sandwiches?

Answer 1

25 students
Pizza - $3
Sandwiches - $2

12 students  x  $3 Pizza = $36
25 students   -  12 students = 13 students bought sandwiches

13 students  x  $2 sandwiches =
$26 spent on sandwiches.

I hope this helps!
