One type of anyifreeze is 40% glycol, and another type of antifreeze is 60% glycol. How much of each kind should be used to make 100 gallons of antifreeze that is 48% glycol? How do i show my work? Thanks

Answer 1

make sure that the amounts of glycol in each part add up to the total.

If there are x gal of 40%, then the rest (100-x) is 60%, so we have

.40x + .60(100-x) = .48(100)
