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:
The estimated GDP in 2007 is 12782 billion dollars.
The estimated GDP in 2011 is 15010 billion dollars.
The estimated GDP in 2012 is 15567 billion dollars.
Step-by-step explanation:
Consider the provided function.
Where y = 10 corresponds to the year 2010.
Part (b) Estimate the GDP (to the nearest billion dollars) in 2007.
If y = 10 corresponds to the year 2010 then y = 7 corresponds to the year 2007.
Substitute the value of y = 7 in the provided function.
Hence, the estimated GDP in 2007 is 12782 billion dollars.
Part (b) Estimate the GDP (to the nearest billion dollars) in 2011.
If y = 10 corresponds to the year 2010 then y = 11 corresponds to the year 2011.
Substitute the value of y = 11 in the provided function.
Hence, the estimated GDP in 2011 is 15010 billion dollars.
Part (C) Estimate the GDP (to the nearest billion dollars) in 2012.
If y = 10 corresponds to the year 2010 then y = 12 corresponds to the year 2012.
Substitute the value of y = 12 in the provided function.
Hence, the estimated GDP in 2012 is 15567 billion dollars.
