Question

There are 278 houses in Hannah's neighborhood. She collected a total of $780 from her neighbors to donate for a local charity. Hannah received $5 at each house she went to. From how many houses did Hannah NOT collect money from? Explain the answer and show your work

Answer 1

1. 780 / 5 = 156
2. 278 - 156 = 122

She did not collect any money from 122 houses.

Answer 2

First, we need to find out how many houses that Hannah received money from. We can do this by dividing the total amount of money she received by the amount she received per house.

780 / 5 = 156

Hannah received money from 156 houses.
To find the amount of houses she did NOT collect money from, we just need to subtract the amount of houses that she DID receive money from away from the total amount of houses in her neighborhood.

278 - 156 = 122

Hannah did not collect money from 122 houses.
Hope this helped! =)
