Answer:
$31.70
Step-by-step explanation:
In order to find the total monthly charge for the customer, you can set up an equation using two different variables and putting in the charges and number of calls for each.
Let 'x' = the number of in-state calls and 'y' = the number of out-of-state calls.
Equation: 0.03x + 0.11y + 10.75 = total
Since the customer made 350 minutes of in-state calls, x = 350 and 95 minutes of out-of-state calls, y = 95:
0.03(350) + 0.11(95) + 10.75 = total
$10.50 + $10.45 + $10.75 = $31.70
Answer:

Step-by-step explanation:
Notice when x increases 1, y is 4 times the previous one, so
the function is like 
To determine the constant C, put any pair of (x, y)
Use x = 0, y = 0.2, so
0.2 =
= C * 1 = C
then 
Answer:
Step-by-step explanation:
K is located at -25
L is located at -15
just move 5 units away from J on both sides

Answer:
50 marbles
Step-by-step explanation: The difference between the ratio of the red and green marbles is 4 units and the number value is 20 so its safe to say that 4 units is equal to 20 and thus one unit is 5 and because of the fact that there is a total of 10 units of marbles in the box according to the ratio, just multiply 5 and 10 which you get 50.
4 units = 20
1 unit = 20÷4 = 5
Total = 10 units
10 unit = 5 ×10 = 50
Ans : 50 marbles
