Sophia has $ 1912.03 left from last month's earnings
<u>Solution:</u>
Given, sophia earned $2,000 last month.
She used 35 of her earnings to pay her bills.
With the remaining money, she bought two shirts for $19.99 each and a pair of earrings for $12.99.
We have to find how much money does Sophia have left from last month's earnings
Now, we know that,
<em>Left money = earned money – used money</em>
= 2000 – (bills paid + 2 shirts cost + 1 pair of ear rings)
= 2000 – (35 + 2 x 19.99 + 12.99)
= 2000 – (35 + 39.98 + 12.99)
= 2000 – (87.97) = 1912.03
Hence, Sophia has $ 1912.03 left with her.

Answer:
-1
Step-by-step explanation:
Tip: Remember to always start from the inside, which would be g(3), in this case.
The first step in solving this problem is to solve for g(3).
To accomplish this, you must substitute 3 for x into the given equation g(x) = x^2 - 10
- g(3) = 3^2 - 10
- g(3) = 9 - 10
- g(3) = -1
The next step is to substitute the answer of g(3), -1, for x in the given equation f(x) = 2x + 1.
Because the equation is asking for f[g(3)], it becomes f(-1) because g(3) = -1.
- f(-1) = 2(-1) + 1
- f(-1) = -2 + 1
- f(-1) = -1
Therefore, f[g(3)], or f(-1), equals -1
