Given data:
The given weight of 1 small cake is w=8.2 ounces.
The numbers of small cakes are n=8.
The total weight of the 8 small cakes is,
W=nxw
Substitute the given values in the above expression.
W=8(8.2 ounces)
=65..2 ounces
=65.2 (0.0625 pound)
=4.1 lb
Thus, the weight of 8 cakes is 4.1 lb, so B) option is correct.
