Answer:
they would have a total of $235 left
Explanation:
add both totals of Mario and Link's go-kart and bike,
which is 565.
then subtract the total of both link's and Mario's allowance from 565,
they have 400 each, so a total of $800.
Which would become 800-565.
So then, Mario and Link would have a total of $235 leftover after buying what they wanted
