At lunch, there was a choice of pizza or burger. Four times as many students chose pizza as chose burgers. Altogether, 150 students got lunch.

Question

Use a strip diagram to determine how many students got pizza and how many got a hamburger. Show all work!

Answer 1

b+4b=150

5b=150=30

Answer 2

Here is your strip: For every 4 students that want pizza, one wants a burger. The blue is the pizza students and the orange is the burger students.

The whole strip represents 150 students. Since 30 + 30 + 30 + 30 + 30, each block in the strip is 30 students.
