So... the radiator has 15 liters of 70% antifreeze.. but needs an 80% antifreeze
well, so, you need to drain some and put some with higher percentage, seems to be, you will end up at the same 15 liters, possible the radiator's capacity, of 80% antifreeze
so, the same amount going out, of 70% is the same amount going in, of 100% antifreeze
now.. let's use the decimal format for the percents, or 70% is 70/100 or 0.7 and so on

so.. let's subtract, from the current solution, 0.7x and add 1x or x, our antifreeze concentration amount, should be 12 though
10.5 - 0.7x + x = 12
solve for "x"

Answer:
B. 
Step-by-step explanation:
Given,
The time for set up the game =
minutes,
Also, the time for each level of game is
minutes,
If there are l levels of games,
Then the time taken in all levels of game = 
Hence, the total time ( in minutes ) = Set up time + time in all level
= 
We have 60-minute of free trial of the game,
So, the total time taken can not be exceed to 60 minutes,

Which is the required inequality.
Option 'B' is correct.
