FRUIT JUICE

n for amount of non-real juice
Formula is 11% real juice, 89% non-real juice
11%2F%2811%2Bn%29=11 and this is a dilution.
Solve for n.



SILVER ALLOY

B = grams of the 55% alloy
E = grams of the 25% alloy
55B%2B25E=40%2A112
and
B%2BE=112

That system can be simplified a bit by dividing the first equation by 5;
11B%2B5E=8%2A112
and
B%2BE=112
Solve the system for B and E.
