Diego Buys 4.25 Pounds Of Mushrooms. Each Pound Costs $\$2.99$. Which Expression Gives The Best Estimate Of The Cost Of The Mushrooms? A. (4)($\$2$) B. (4)($\$3$) C. (5)($\$2$) D.
Introduction
Diego buys 4.25 pounds of mushrooms, and each pound costs $2.99. To find the best estimate of the cost of the mushrooms, we need to calculate the total cost. In this article, we will explore the different options and determine which expression gives the best estimate of the cost.
Understanding the Problem
The problem requires us to find the total cost of 4.25 pounds of mushrooms, given that each pound costs $2.99. To solve this problem, we need to multiply the number of pounds by the cost per pound.
Option A: (4)($$$)
Option A suggests multiplying 4 by $2. This is a simple calculation, but it does not take into account the fact that Diego bought 4.25 pounds of mushrooms, not 4 pounds. Therefore, this option is not the best estimate of the cost.
Option B: (4)($$$)
Option B suggests multiplying 4 by $3. This is still not the best estimate, as it does not take into account the fact that Diego bought 4.25 pounds of mushrooms. However, this option is closer to the actual cost than Option A.
Option C: (5)($$$)
Option C suggests multiplying 5 by $2. This option is closer to the actual cost than Options A and B, as it takes into account the fact that Diego bought 4.25 pounds of mushrooms, which is approximately 5 pounds. However, this option is still not the best estimate, as it does not account for the remaining 0.25 pounds.
The Best Estimate
To find the best estimate of the cost, we need to round the number of pounds to the nearest whole number. In this case, 4.25 pounds is closer to 5 pounds than 4 pounds. Therefore, the best estimate of the cost is to multiply 5 by $2.99, which is the cost per pound.
Conclusion
In conclusion, the best estimate of the cost of the mushrooms is to multiply 5 by $2.99. This option takes into account the fact that Diego bought 4.25 pounds of mushrooms, which is approximately 5 pounds. Therefore, the correct answer is:
C. (5)($$$)
