$f(x)=2x^2-8x+6=2(x^2-4x+3)\\\\=2(x^2-2x\cdot2+4-1)=2(x^2-2x\cdot2+2^2-1)\\\\=2[(x-2)^2-1]=2(x-2)^2+2\cdot(-1)=2(x-2)^2-2\\-------------------------\\f(x)=a(x-k)^2+h\to the\ vertex:(k;\ h)\\\\therefore\ the\ coordinates\ of\ the\ vertex:(2;-2)\\a=2\ to\ the\ minimum.\\\\Your\ \boxed{Minimum:(2;-2)}$

12 dimes

Step-by-step explanation:

1 dollar= 4 quarters

1 dime=10 cents

3.45-1.20=2.25

2 dollars= 8 quarters

2.25-2.20=.25

1 quarter=.25

S your answer is 12 dimes
