Question

wandas dad has owned an ice cream shop for more than 25 years. last week, one of his freezers stopped working, and he needs to buy a replacement. he is considering three different freezer options. the lowest temperature setting for each freezer is shown in the table.

freezer	temperature (°f)
model ftr 2.1	-15
model ftr 2.5	-22

which freezer offers the lowest temperature setting?

options: model ftr 2.0, model ftr 2.1, model ftr 2.5

Explanation:

Step1: Recall negative number comparison

To compare negative temperatures, the more negative a number is, the lower the temperature. So we compare -20, -15, and -22.

Step2: Compare the numbers

We know that for negative integers, the larger the absolute value, the smaller the number. \(|-22| = 22\), \(|-20| = 20\), \(|-15| = 15\). Since \(22>20>15\), then \(-22 < -20 < -15\). So -22 (Model FTR 2.5) is the lowest.

Answer:

Model FTR 2.5
