x=440 gaL 90 % Antifreeze II
Step-by-step explanation:
In the problem, there are two types of antifreeze
antifreeeze I and
antifreeze II
antifreeze I 25 ----80 gal
Antifreeze II 90 ----- x gal
Total 80 ---------------- (80 + x ) gal
(25*80)+(90*x)=80(80+x)
2000+90x=6400+80x
90x-80x=6400-2000
10x=4400
divide both sides by 10 we have
x= 440
x=440 gaL 90 % Antifreeze II
