Introduction

In this article, we will explore the concept of estimating the cost of strawberries based on a given quantity and price. Manuel buys 7.9 pounds of strawberries, and each pound costs $\$3.89$ . We need to find the best estimate of the cost of the strawberries. To do this, we will examine different mathematical expressions and determine which one provides the most accurate estimate.

Understanding the Problem

The problem requires us to find the cost of 7.9 pounds of strawberries, given that each pound costs $\$3.89$ . To estimate the cost, we can use the concept of multiplication. We can multiply the number of pounds by the cost per pound to get the total cost.

Analyzing the Options

Let's analyze the given options:

A. (8)($4) B. (7)($$4) C. (8)($$3) D. (7)($3)

We need to determine which expression gives the best estimate of the cost of the strawberries.

Option A: (8)($4)

Option A involves multiplying 8 by $\$4$ . This expression is not accurate because it assumes that Manuel bought 8 pounds of strawberries, which is not the case. The actual quantity is 7.9 pounds.

Option B: (7)($$4)

Option B involves multiplying 7 by $\$4$ . This expression is also not accurate because it assumes that the cost per pound is $\$4$ , which is not the case. The actual cost per pound is $\$3.89$ .

Option C: (8)($$3)

Option C involves multiplying 8 by $\$3$ . This expression is not accurate because it assumes that Manuel bought 8 pounds of strawberries, which is not the case. The actual quantity is 7.9 pounds.

Option D: (7)($3)

Option D involves multiplying 7 by $\$3$ . This expression is the most accurate because it takes into account the actual quantity of strawberries (7.9 pounds) and the actual cost per pound ( $\$3.89$ ). However, since we are estimating, we can round the quantity to the nearest whole number, which is 8 pounds. Therefore, the expression (8)($3) provides the best estimate of the cost of the strawberries.

Conclusion

In conclusion, the best estimate of the cost of the strawberries is given by the expression (8)($3). This expression takes into account the actual quantity of strawberries (7.9 pounds) and the actual cost per pound ( $\$3.89$ ). By rounding the quantity to the nearest whole number, we can get a more accurate estimate of the cost.

Final Answer

The final answer is:

(8)($3)

Why This Answer is Correct

This answer is correct because it takes into account the actual quantity of strawberries (7.9 pounds) and the actual cost per pound ( $\$3.89$ ). By rounding the quantity to the nearest whole number, we can get a more accurate estimate of the cost.
