Answer:

52

Step-by-step explanation:

Alex earned 156 reward points for selling wrapping paper rolls.

Using the given equation

3r = 156

r = 156/3

r = 52

Alex sold 52 wrapping paper rolls

The answer would be 2431.

<span>Given:

Last balance-$98.32

payments-$30,

finance rate-1.5%

new charges-$58.28

98.32 - 30 = 68.32

68.32 * 1.5% = 1.0248

</span><span>The finance charge on the unpaid balance is $1.02

Only the remaining balance of the last balance shall be subjected to finance charge. The finance charge will be added to the balance that will be paid next due date. In the event that partial payment will still be made, the remaining balance will still be subjected to finance charge.

**Answer:**

Odd function

**Step-by-step explanation:**

The given function is

**We know that:**

- The function is even if f(-x) = f(x)

- The function is odd if f(-x)=-f(x)
- If the function doesn't satisfy these two properties then it is neither odd nor even.

**Hence, we substitute x = -x to find f(-x)**

**Since, f(-x)=-f(x). Hence, the function is odd.**
