10. Mr. Hanson is preparing an activity for his

Anna71 [15]

Answer:

Step-by-step explanation:

Out of all of the answers provided, H seems like the equation that makes the most sense.

$(60 * 3) = 180$

$[480 - (180)] = 300$

$300 = 60$

Make sure you divide 300 sticks by 60 sticks (box max) to get the number of boxes.

$300 / 60 = 5$

So, Mr. Hanson would need to have 5 more boxes in order to get the total amount of 480 sticks.

From that, H would be considered the best equation that Mr. Hanson would use.
