Answer:
if it's less than 7.66km use Royal, if more than 7.66 use Queen's
Step-by-step explanation:
To get the answer you can set up mutliple equations
For Queen's Cab Company
2.70 + 0.20x = ?
for Royal Cab Company
1.55 + 0.35x = ?
Since you didn't give a distance which is what will determine which is cheaper we can solve as a set of equations.
2.70 + 0.20x = 1.55 + 0.35x
1.15 = .15x
x = 7.66
So this lets you know that at 7.66 km Royal cab company becomes more expensive due to their pence per km.
So if it's less than 7.66km use Royal, if more use Queen's
Data? I need the data! Not trying to provoke, but in order to answer this I need data...
1. it helps you by being the first number you use to divide
2 you can multiply the quotient and dividend to check your answer so you can check if the quotient is right, to see if its right it should equal the divisor.

So your friend bought 1 set of brush and 5 bottles of paint
you bought 2 brushes and 7 bottles of paint
1 bottle=3.69
friends cost+your cost=51.69
total you bought 3 brushes and 12 bottles
each bottle is 3.69
12*3.69=44.28
totalcost=51.69=3brushes+12bottles
51.69=3brushes+44.28
minus 44.28 from both sides
7.41=3brushes
divide both sides by 3
2.47=1brush
1 set of paint brushes=$2.47
