d

anonymous · Answer

it should technically be 126-30=b but with that equation you can solve for b

anonymous · Answer

so im confused now is it b or d?

jdoe0001 · Answer

you see, Oscar is a spendthrift, he's been borrowing from Lucille for a while now and owes her "b" already
so now he's borrowing YET $30 more, on top of what he already borrowed, "b amount"
so we don't know how much he's been borrowing, but we now know that after the $30 he just borrowed from Lucille, he owes her $126

jdoe0001 · Answer

before borrowing $30 from her, he owed her "b"
after borrowing $30 from her, he owed her, "b + 30" which we now know is $126
