The average temperature of Kopikoville was reported to be - 20° last year. This year, the average temperature of Kopikoville rose by 6°. Which of the following is true about this year's average temperature of Kopikoville?

A. This year's average temperature of Kopikoville is 26°.
B. This year's average temperature of Kopikoville is 14°.
C. This year's average temperature of Kopikoville is - 26°.
D. This year's average temperature of Kopikoville is - 14°.

Answer 1

- 14

Explanation:

This is a place I sure don't want to live in. The summer probably has all sorts of disagreeable insects like mosquitoes and horseflies.

If the average temperature rose by 6 degrees then just add 6 onto - 20

- 20 + 6 = - 14

Note that rose means add. Think money. If you owe someone 20 dollars your net value is - 20. You could say your debt is 20.

If you cut someone's grass and they give you 6 dollars, then your net worth is - 20 + 6 = - 14. You still owe money. Just not as much.
