36% of 80

First, you multiply 36 and 80.

36*80 = 2880

Now, we divide that by 100.

2880/100 = 28.8

Our final answer: 28.8

skad [1K]

We do
concentration=amount times percent
total concentration=concentration8+concenctration20

so
12 times 8%+x times 20%=16% times (12+x)

x=amount of 20% acis solution

12*0.08+0.2*x=0.16*(12+x)
solve
distribute and simplify
0.96+0.2x=1.92+0.16x
minus 0.96 from both sides
0.20x=0.96+0.16x
minus 0.16x from both sides
0.04x=0.96
divide both sides by 0.04
x=24
