Answer:

18 - (-12)

Step-by-step explanation:

Final temp. - Initial temp. = the change in temperature

By -12, we're indicating that is below zero (which is obvious) meaning that it is not in the "normal" scale nor in the imaginary scale of numbers. So, we can operate the following...

18 - (-12) = 30

So the temperature changed by 30 values or the temperature increased by 30 values, because the number is positive.

soldi70 [24.7K]

Given:

Goal = 250 cans

Number of collected cans = 290

To find:

The percent of their goal they achieved.

Solution:

The percent of their goal they achieved is:

\text{Required percent}=\dfrac{\text{Number of collected cans}}{\text{Goal}}\times 100

\text{Required percent}=\dfrac{290}{250}\times 100

\text{Required percent}=\dfrac{29}{25}\times 100

\text{Required percent}=29\times 4

\text{Required percent}=116

Therefore, they achieved 116% of their goal.
