<h2>Answer:</h2><h2>(i) Total expenses = $ 300</h2><h2>(ii) Net income(savings) = $ 0</h2>

Step-by-step explanation:

Total income earned by Sam = $ 300

(i) Expense calculation,

Clothes expense = 30 % = 30 % (300) = $ 90

Food and snacks expense = 23 % = 23 % (300) = $ 69

Cell phone expense = 14% = 14% (300) = $ 42

Transportation expense = 10% = 10% (300) = $ 30

Gym expense = 10% = $ 30

Movies expense = 8% = 8% (300) = $ 24

Apps expense = 5% = 5% (300) = $ 15

Total expenses = (90 + 69 + 42 + 30 + 30 + 24 + 15) = $ 300

(ii) Sam's net income is the profir earned after his expense.

Net income = 300 - 300 = $ 0

Answer:

C. 52°

Step-by-step explanation:

In ∆CAB, m<A = right angle = 90°

m<B = 38°

m<C + m<A + m<B = 180° (sum of ∆)

m<C + 90° + 38° = 180° (substitution)

m<C + 128 = 180

m<C = 180 - 128 (subtraction property of equality)

m<C = 52°

Chang and Carlotta solve this problem in two different ways. You have $50 in your bank account. You make $8 per hour mowing lawn

Tamiku [17]

HELLO,

Your answer is 130-50=80
You would have to make 80 dollars,

So 8 dollars per hour (of course that is below minimum wage that means you need a raise).

Therefore, you need to mow lawns for 10 hours

Thanks for posting your question here on brainly.
Hope this helps you.
Let me know if its correct.

Given the values of the linear functions f (x) and g(x) in the tables, where is (f – g)(x) positive?

alexandr402 [8]

Comparing the functions, from the tables, it is found that (f - g)(x) is positive in the interval (–∞, 9) .

----------------------

For the subtraction function, we simply subtract both functions, thus:

$(f - g)(x) = f(x) - g(x)$

It is positive if f is greater than g, that is: f(x) > g(x).
It is a linear function, so one function is greater before the equality, one after.
They are equal at x = 9.
If x < 9, f(x) > g(x), and thus, (f - g)(x) is positive, which means that the desired interval is:

(–∞, 9)
