Question

Priya and Han plan a fundraiser for the running club. They begin with a balance of - 80 because of expenses. In the first hour of the fundraiser they collect equal donations from 9 family members, which brings their balance to -44. How much did each parent give?

Answer 1

Each family member/parent gave 4.

Explanation:

Subtract -44 from -80 (-80 - -44) to get -36, the negative amount the parents gave. Then divide -36 by 9 (the number of parents) to get -4. Get rid of the negative sign since the parents are giving money, not taking it away. This leaves you with 4 per parent.

To double-check your work, you can do -4 x 9 which equals -36, then add -44 to get you back to -80, the original debt Priya and Han were in.

Hope this helps! :D

Answer 2

4 units of money

-----------------------------------

The beginning balance is -80 and ending balance after the first hour is -44.

The difference is:

• - 44 - (- 80) = 36

This increase belongs to 9 family members.

Each of them donated:

• 36/9 = 4
