For her birthday party Danielle mixed
together 3 gal. of Brand A fruit punch and 7
gal. of apple juice.
If Brand A contains 20%
fruit juice, then what percent of the final
mixture is fruit juice?
-----
Equation:
fruit juice + fruit juice = fruit juice
0.20*3 + 1*7 = x(3+7)
-----
20*3 + 100*7 = 1000x
-------
760/1000 = x
-----
Ans: x = 0.760 = 76%
