Question

Mrs. Nelson is buying bottles of hand sanitizer for her employees. She already has 25 bottles in her office and needs a total of 200 bottles. They are sold in boxes of 20. Write an equation to show how many more boxes of hand sanitizer she needs.

Answer 1

Answer: (200-25)/20

Explanation:

Since Mrs. Nelson already has 25 bottles in her office, she only needs 200-25 bottles for her employees. This becomes the first part of our equation.

Secondly, we must find the amount of boxes she needs, shown by dividing the amount of boxes in which they are sold (20) into the amount of bottles needed (200-25). Thus, we are left with the equation (200-25)/20.

Hope this helps!

Answer 2

(200-25)=x/20

Explanation: she needs a total of 200

She already has 25 so you’d subtract 25 from 200

You don’t know how many bottles you need yet so that would be x.

X is divided by 20 since it comes in a box of 20.

X=175/20 which would be 8.75 or rounded up to 9
