Answer:
6×5×4×0 = 0
Step-by-step explanation:
In order for a product to be zero, one (or more) of the factors must be zero. You can pick any numbers you like for the factors, but one of them must evaluate to zero.
0 = 0·3·2·1
0 = -85·(3 -2 -1)
N = 0
-7 + 3n = -7 - 3n
-7 + 6n = -7
6n = 0
n = 0
Set up a proportion and then cross multiply to solve. OR. 15/5 = $3 per bag is the unit rate per 1 bag.
Multiply 27*3=$81
