Which of the following strategies might Eve use to determine which package to buy? Use the strategy to solve the problem. mental math, number sense, estimation​

Answer 1

Eve should purchase four 0.5-pound packages of feta cheese to obtain the exact 2 pounds needed for her pizza recipe using mental math and estimation.

Step-by-step explanation:

Eve is planning to make a pizza that requires 2 pounds of feta cheese. The store offers different package sizes for feta cheese, specifically 0.375-pound and 0.5-pound packages. To determine which package she should buy to reach a total of 2 pounds, Eve can use mental math, number sense, and estimation.

First, she could estimate that four 0.5-pound packages would equal 2 pounds (0.5 + 0.5 + 0.5 + 0.5 = 2), which is a straightforward solution using mental math. Alternatively, considering the 0.375-pound packages, she would need to buy a multiple of 0.375 that equals 2 pounds, but since there is no whole number that 0.375 can be multiplied by to equal exactly 2, this strategy is less efficient for her needs.

Given these options, Eve should purchase four 0.5-pound packages of feta cheese to get the exact amount she needs for her recipe. This approach implements simple arithmetic and the ability to estimate quantities, both of which are useful skills in everyday decision-making scenarios like grocery shopping.
