Can anyone help me with my math? Its Algebra 2! :(

There are people here who can help with levels of math even higher than that. But you have to tell us what you need help with.

You can post a problem which you don't know how to solve. However, it's better to show also what you have tried to do, so that we can spot where is exactly your problem :)

For extremely cold temperatures, an automobilemanufacturer recommends that a 80% antifreeze and 20% water mix be used in the coolingsystem of a car. How many quarts of pure (100%) antifreeze and 50% antifreezeand 50% water mix should be combined to make 11 quarts of 80% antifreeze and20% water mix?

? Qt of 100% antifreeze; ? Qt of 50% − 50%mix

A) 294 qt of 100% antifreeze; − 148qt of 50% −50% mix

B) 249 qt of 100% antifreeze; − 141 qt of 50% −50% mix

C) 430 qt of 100% antifreeze; − 420qt of 50% −50% mix

D) 429 qt of 100% antifreeze; − 418 qt of 50% −50% mix

Please help me I don't know how to do this?:confused:
