formula
long side×short side=area of this rectangle
N=3 m+7
n-2 m=1 | -2 m => n=1+2m
n=3 <span>m+7
</span><span>n=1+2 m
</span>
n=n
3m+7=1+2m |-7 and -2m
m = -6
n=1+2m
n=1+2*(-6)
n=-11

Answer:
Dozen Oatmeal = $4 and Dozen Chocolate = $9
Step-by-step explanation:
Dozen Oatmeal:
10 dozen oatmeal and 1 dozen chocolate =$49
9 dozen oatmeal and 1 dozen chocolate = $45
The second customer bought 1 less dozen and paid $4 fewer dollars, therefore 1 dozen oatmeal must equal $4
Dozen Chocolate: let C = 1 dozen chocolate
10 dozen oatmeal + 1 dozen chocolate = $49
(10 x $4) + C = $49
$40 + C = $49
-40 -40
C = $9
1 dozen chocolate cookies = $9
