Answer:
96 ways
Step-by-step explanation:
Let´s call flags of countries from Africa as A₁, A₂, A₃, A₄, and from Europe as E₁, E₂, E₃ and E₄
We have to display the flags always beginning with one flag from Africa let´s take A₁
For that flag, we have 4! possibilities Then 4! is:
4*3*2*1 = 24
As we have 4 different Flags from Africa, we will have
4*24 = 96 possibilities
24.69 x 12 = 296.28
296.28 x 1.06 = 314.06
With tax and everything, the total bill rounds up to $314.06. Hope this helped!
Let's apply BPT theorem(Not necessary we can apply common ratios and similarities)
Put values
Option B
Let's solve it out
For 3 minutes, 4.8 gallons
The amount per minute of gallons is 1.6 (0.8x2). So amount per minute times 3 is 1.6 times 3 = 4.8
