We will say that d = 1 dozen. and y = cost
we know that 3 dozen is 48. so
3d = 48.
to get the cost of 1d, we have to get the 3 to change into a 1. the only way to do this is to divide 3 by 3. if we divided the left side by 3 we must also do the right so:
3d = 48
1d = 16
so 1 dozen = 16
to change 3d into 9d we have to multiply by 3. we again have to do this to both sides. so:
3d = 48
9d = 144
A=Y^6
B=7^4•n^5•m
C=y^4
D=t^4
20 plus 24
Divided by 15
Which gets you to
44 over 15 or 2 wholes and 14 over 15
