Ayo fam, let's break it down for ya. Noah's rollin' with 20 bucks in his pocket, right? He's gotta cop 3 gifts.
For gift A, my dude spends 8 1/4 dollars. That's like eight dollars and then a quarter - you feel me? So it’s $8.25 when you make it all decimal and stuff.
For gift B, he’s dropping 3 4/5 dollars. That's three dollars and then four-fifths of another dollar. Converting that fraction, it's $3.80.
So Noah's gotta make his dollars stretch. He’s spent $8.25 on the first gift and $3.80 on the second. Let’s add that up real quick: 8.25 + 3.80 = $12.05.
Now, let’s check how much dough he’s got left for gift C. He started with $20, and he’s used $12.05. Subtract to find out: 20 - 12.05 = $7.95.
So my guy Noah’s got $7.95 left to spend on gift C. He's gotta make it count!
