Leon graph y=12- 0.05 x to represent the number of gallons of gas left in his car after driving x miles.
mario62 [17]

Answer:

B

Step-by-step explanation:

Range of the graph is the ALLOWED y-values. The y-axis is number of gallons left in tank. So, <u><em>it cannot be NEGATIVE number of gallons, so 0 is the lower limit of the range.</em></u>

<u><em /></u>

As we can see from the axis of the graph, we see where the line cuts the y-axis, that is the upper limit of number of gallons he starts off with. The y-intercept (y-axis cutting point) is 12.

So we can say that the range is  0 ≤ y ≤ 12

Correct answer is B

<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
