Answer 2

The range of this relation is equal to: C. {20, 30, 40, 50, 60, 70, 80}

What is a range?

In Mathematics, a range simply refers to the difference between the highest number and the lowest number contained in a data set.

Mathematically, range can be calculated by using this formula;

Range = Highest number - Lowest number

Since 20 loaves of wheat bread are baked before the bakery opens at 7 AM and 10 more loaves every half-hour (30 minutes) for the next three hours, it simply means it would bake 10 more loaves in six (6) places.

Range = {20, 30, 40, 50, 60, 70, 80}
