Question

Manuel buys 7.9 pounds of strawberries. Each pound costs $3.89. Which expression gives the best estimate of the cost of the strawberries?
(8)($4)
(7)($4)
(8)($3)
(7)($3)

Answer 1

To estimate the cost of 7.9 pounds of strawberries at $3.89 per pound, you can round 7.9 to 8 and $3.89 to $4.

Thus, the best expression for estimating the cost would be:
\[
(8) \times (4)
\]

So the correct choice is:
\((8)($4)\)
