2. (04.05 MC) The price of fuel may increase due to demand and decrease due to overproduction. Marco is studying the change in the price of two types of fuel, A and B, over time. The price f(x), in dollars, of fuel A after x months is represented by the function below: f(x) = 2.15(0.98)x Part A: Is the price of fuel A increasing or decreasing and by what percentage per month? Justify your answer. (5 points) Part B: The table below shows the price g(m), in dollars, of fuel B after m months. m (number of months) 1 2 3 4 g(m) (price in dollars) 4.19 3.98 3.78 3.59 Which type of fuel recorded a greater percentage change in price over the previous month? Justify your answer. (5 points) (10 points)

step-by-step explanation:

always plug in x. in this case, x equals 4.

i'm going to first solve 4(2+3x)

1) 4(2+3(4)) use pemdas to solve.

i'm going to multiply whats in the parenthesis first, so 3 times 4=12.

2)4 (2+12) i'm then going to multiply 4 by both numbers in the parenthesis (because multiplying comes before adding)

4 times 2= 8.   4 times 12= 48

4) (8+48)= 56 (answer)

i'm then going to solve 8+12x and plug in 4 for x.

1) 8 +12(4)

multiplying comes before adding, so i'm gonna multiply 12 and 4.

12 times 4= 48.

2) 8+48=56

both equal the same!

57.09 minus 7.0435 equals

step-by-step explanation:

just subtrach them both and u get the answer of 50.0465

none of these

step-by-step explanation:

23 + 34 add up to 57 so just inform the teacher of this really stupid mistake
