The price of blackberries at a farm is $1.56 per pound. which equation can be used to determine c, the total price of n pounds of blackberries?

c = 1.56n
c = 1.56 over n
c = 1.56 + n
c = 1.56 − n

The equation which can be used to determine c, the total price of n pounds of blackberries is:

                             c = 1.56n

The cost of 1 pound of blackberries is: $ 1.56

( since, it was given that: The price of blackberries at a farm is $1.56 per pound )

Also we know that the cost of n pound of blackberries is the product of number of pounds of blackberries to cost of one pound of blackberries.

Hence, the cost of n pounds of blackberries is:

                      c=1.56n

if you mean

then it's c. 8, -7/3

but if you mean

then it is
