Acoffee mixture has beans that sell for $1.35 per pound and beans that sell for $1.05 per pound. if 120 pounds of beans create a mixture worth $1.15 per pound, how many pounds of each bean is used? a) 50 lb of $1.35/lb; 70 lb of $1.05/lb b) 40 lb of $1.35/lb; 80 lb of $1.05/lb c) 45 lb of $1.35/lb; 75 lb of $1.05/lb

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.
