Let x=gallons of 80% solution to be mixed
x+80=gallons go final 70% mixture
..
80%*x+30%*80=70%*(x+80)
.8x+24=.7x+56
.1x=32
x=320
gallons of 80% solution to be mixed=320
Answer:
9/64
Step-by-step explanation:
For similar triangles, the ratio of areas is the square of the ratio of corresponding sides.
__
The ratio of areas is (3/8)² = 9/64.
A=6,500×(1+0.07÷360)^(360×5)
A=9,223.63
Interest earned
9223.63-6500==2,723.63
