Answer:
Brand A is the better buy
Step-by-step explanation:
bag Which is the better buy?
Step one
Brand A: $5 for 80 pounds of sand
Let us find the unit cost
Unit cost =5/80
=$0.0625 per pound
Brand B: $14 for 175 pound
The unit cost is
=14/175
=$0.08 per pound
93/3 = 31, 31 x 4= 124
Calories per cup is 124
There are 372 calories in three cups
There was 16 bagels, and now there is 0 bagels. So what you do is subtract 16 from 16 to get 0.
