Question

A pitcher of water contains 8 ice cubes. Each ice cube lowers the water's temperature by 2 degrees, which can be expressed as (-2). If an ice cube is removed, the temperature is raised by -(-2). Consider 3 ice cubes being removed from the pitcher. The total rise in temperature is

A) -(-4)°, which is the same as 4°.
B) -(-2)°, which is the same as 2°.
C) -3(2)°, which is the same as -6°
D) -3(-2)°, which is the same as 6°.

Answer 1

At first I thought I had to make a graph but yeah it's D since there are 3 and they are negative degrees

Answer 2

If removing 1 ice cube raises the temperature by -(-2), then removing 3 ice cubes would raise the temp

-3(-2) = 6 degrees

Answer D
