Richard and his friend Julie collect coins as a hobby. Richard has 8 more coins than Julie. If they have 28 altogether how many coins did Julie have?

Julie had 10 coins

Step-by-step explanation:

Since there are 28 coins and Richard has 8 more coins than Julie

You can subtract 8 from 28 and get 20

then you would divide 20 by 2 since there are two people( Richard and Julie)  Which would give you 10

Since Richard has 8 more coins and each of them have ten you would add 8 to the 10 and you would get 18

Meaning that Richard had 18 coins and Julie had 10 coins
