Answer:
The best estimate for the cost of each pound of flour is that a pound is $1.89.
Explanation:
15.86 is the total amount for 8.4 pounds of flour. So to find the cost of each pound of flour or the unit price, you divide how much flour there is to the total.
15.86/8.4=1.88571428571
And rounded up the cost of each pound of flour is $1.89.
