E. Engagement Time Frame: Dox2) Leaming Task 2: Mate lists of possible combinations of snacks in your notebook. Use O for Orange Juice, M for Mango Juice, B for Blue Lemonade, O for Oreo, s for Skyflakes and R for Rebisco. Juices Biscuit Orange Juice Oreo Mango Juice Skyflakes Blue Leronode Rebisco​

The maximum number of possible combinations are 9.

Step-by-step explanation:

There are three types of juices :

Orange, Mango and Blue lemonade

There are three types of biscuits:

Oreo, Skyflakes and Rebisco

So, the number of possible combinations are

= (3 C 1) x (3 C 1)

= 3 x 3 = 9

The maximum number of possible combinations are 9.

Part A:

Given that the growth factor of x (the number of months) is a positive number larger than 1, we have that as the number of months increases, the price of fuel also increases

Therefore, the price of fuel A is increasing, by 4% each month

Part B:

Fuel B records a greater percentage change in price over the previous month.

Step-by-step explanation:

The function that represents the price of fuel A is f(x) = 2.96(1.04)ˣ

Where;

x = The number of months

Part A: Given that the growth factor of x (the number of months) is a positive number larger than 1, we have that as the number of months increases, the price of fuel also increases

Therefore, the price of fuel A is increasing

(2.96(1.04)² - 2.96(1.04)¹)/(2.96(1.04)¹) × 100 = 4 %

(2.96(1.04)³ - 2.96(1.04)²)/(2.96(1.04)²) × 100 = 4 %

(2.96(1.04)⁴ - 2.96(1.04)³)/(2.96(1.04)³) × 100 = 4 %

Part B: The given table is presented as follows;

Months, m                                 The price of fuel, g(m)

1                                                   3.04

2                                                  3.22

3                                                   3.41

4                                                   3.61

The percentage change in price for fuel A over the previous month is given as follows;

Fuel price of fuel A in the previous month f(3) = 2.96(1.04)³≈ $3.33

Fuel price of fuel A in the current month f(4) = 2.96(1.04)⁴ ≈ $3.463

The percentage change in price = (3.463 - 3.33)/3.33 × 100 ≈ 4 % change

The percentage change in price for fuel B over the previous month is given as follows;

Fuel price of fuel B in the previous month = $3.41

Fuel price of fuel B in the current month = $3.61

The percentage change in price = (3.61 - 3.41)/3.41 × 100 ≈ 5.865 % change

Therefore, fuel B recorded a greater percentage change in price of 5.865 %, over the previous month than fuel A with a percentage change in price of 4 %

Fuel B records a greater percentage change in price over the previous month.
