Start by dividing both sides by 2 to get
. Doing the math on the right, keeping in mind that logs have an unwritten base of 10, gives us
. Rewriting this in exponential form is
. That means that x = 8. Not negative, only positive.
So you have to subtract 115 from 15. Then you divide that number by 5 for each relative. That should give you your answer....$20
