For the same reason that a man is always a person but a person
is not always a man.
And the same reason that a 5th grader is always a student but a student
is not always a 5th grader.
A square is a special kind of rectangle ... one with all equal sides. If all the
sides are not equal, then it's still a rectangle, but it's no longer the 'special'
kind of rectangle.
We would first simplify all the proportions by treating them as fractions
8:12=2:3
6:9=2:3
10:14=5:7
12:16=3:4
64:144=4:9
obviously 8:12 and 6:9 are in proportion so the answer is A
5x$12= 60$ so 60$per week 60$x12 = $720 for the Medium dogs.
8x14$= 112$ per week, she walked them 12 weeks. 112x12= $1344 for the large dogs.
Now take the two prices $720+$1344= $2,064
She earned a total of $2,064 from walking the dogs.
Hope this helped.
