There were 135 cars in a rally each driver paid a $25 fee to participate in the rally how much money did the drivers play in all

Total numbers of cars present in the rally is  135

Amount paid by a single driver to participate in the rally = $25

Total amount generated by the participation fee from each driver is equal to the sum of amount paid by all the 135 cars.

Since we cannot add $25 for 135 times, we use multiplication operation.

Total amount = amount paid by one single driver multiplied by the total number of cars.

Total amount = $ .... Answer

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.
