Question 1095027

Fred has $120 more than Bob. After Fred spends $20 on groceries, Fred has 6 times as much money as Bob. How much money does Bob have?
<pre>Let amount Bob has be B
Then Fred has: B + 120
We then get: B + 120 - 20 = 6B
100 = 5B
B, or amount Bob has = {{{highlight_green(matrix(1,3, 100/5, "=", "$20"))}}}
