If a car covers 82.5 km in 5.5L of gas, how much distance will it cover in 13.2L of gas?

198km

Step-by-step explanation:

The distance covered is directly proportional to the litres of petrol.

Let a distance covered with 13.2 litres of petrol

So,  ⇒5.5:13.2=82.5:a

Applying the rule, product of extremes = product of means

⇒5.5×a=13.2×82.5

⇒a= 13.2×82.5/ 5.5

⇒a=198

Hence, the distance covered with 13.2 litres of petrol is 198 km.

actually your concept is wrong

step-by-step explanation:

150% of x =300

150x=300×100

x=(300×100)÷150

x=200

take the logarithm of both sides (the base of the log doesn't matter):

apply the exponent property - this says that :

distribute the log terms on both sides:

group like terms together:

divide through both sides by the coefficient on :

you can do some additional rewriting here using the properties of the logarithm to simplify things if you like:
