Question

In 2015, the total rainfall in central city was 13 inches less than the total annual rainfall in central city in 2000. In 2016, the total rainfall was 33 inches greater than the total rainfall in 2000. If + indicates an increase in rainfall and - indicates a decrease, what was the difference, in inches, in the yearly rainfall from 2015 to 2016?

1) -46
2) -20
3) +10
4) +20
5) +46

Answer 1

To find the difference in yearly rainfall from 2015 to 2016, subtract the rainfall in 2015 from the rainfall in 2016. The difference is +46 inches.

So, the correct answer is Option 5.

Step-by-step explanation:

To find the difference in yearly rainfall from 2015 to 2016, we need to calculate the total annual rainfall in each year and then subtract them. Let's start with the rainfall in 2015. We know that in 2015, the total rainfall in central city was 13 inches less than in 2000. So, if we call the rainfall in 2000 as 'R', then the rainfall in 2015 would be 'R - 13'.

Similarly, in 2016, the total rainfall was 33 inches greater than in 2000. So, the rainfall in 2016 would be 'R + 33'.

Now, to find the difference in rainfall from 2015 to 2016, we subtract the rainfall in 2015 from the rainfall in 2016:

(R + 33) - (R - 13) = 33 - (-13) = 33 + 13 = 46.

Therefore, the difference in the yearly rainfall from 2015 to 2016 is +46 inches.

So, the correct answer is Option 5.
