Another way of saying " Derrick spends $7 less than Alan" is "Alan spends $7 more than Derrick"
Alan earns $12 more than Derrick, but Alan also spends $7 more than Derrick, so you have to minus to see how much more Alan earns!
Everyday, there will be a common difference of $5 !
Hope you can understand!
