Question

Miss Violet is buying granola bars for her students. She already has 16 granola bars in her desk and needs a total of 100 bars. They are sold in packs of 12. Write an equation to show how many more boxes of granola bars she needs.

16 – 12x = 100
16 – 12x = 100

16x + 12 = 100
16x + 12 = 100

16 + 12x = 100
16 + 12x = 100

12x – 16 = 100
12x – 16 = 100

Answer 1

She need 7

Explanation:

12x7=84

Then add 16 to 84 to get 100

Answer 2

100 - 16 = 84, and 84 divided by 12 is 7. She needs to buy 7 more boxes of granola bars for her students.
