u+16> 20 or u+20 < 14
first u +16>20
subtract 16 from each side
u > 4
u+20 < 14
subtract 20 from each side
u < -6
so.....
u < -6 or u > 4
Mom's view is that she loses 50 dollars, but gains back 17.85 dollars as change from her daughter.
Olivia's view is that she gained 50 dollars from her mom, spent 32.15 dollars, then gave back the 17.85 change to her mom, so she didn't gain any money.
Mom's point of view: -$50 + $17.85 and Mom's point of view: -$50 + $17.85 are the correct answers, but technically, Olivia still owes her mom 32.15 dollars.

Let's represent Nemo's age with an n.
Barney is 8 years older so his age is nemo's plus 8. That is, Barney's age is n + 8
In seven years they will each be the age they are now plus 7. So, Nemo will be n + 7 and Barney will be n + 8 + 7. If the sum of their ages will be 46 we know that when we add these expressions we should get 46, so let's set the sum to 46 and solve for n.
n + 7 + n + 8 + 7 = 46
2n + 22 = 46
2n = 46 - 22
2n = 24
n = 12
That means that Nemo's age is 12.
Since Barney is 8 years older his age is 12 + 8 = 20.
To check our work we see that in 7 years Nemo will be 12 + 7 = 19 and Barney will be 20 + 7 = 27. Together that is 19 +27 = 46 as expected.
