Think about it in terms of "what are we multiplying by?".
In case 1), you multiply by $1.052$
In case 2) you multiply by $.9875$
So multiply all four of those factors together.
Then figure out what other number could you multiply by itself 4 times to get the same result. I'll show a formula if that doesn't make sense or you can't work through that.
