Hope that helped!
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
0.3m=$4.41
just divide $4.41/0.3= m
m=14.7
The residual value is -1.14.
Plug 5 into x
y=-0.7(5)+2.36
=-1.14
