The problem above shows a "direct proportion," which means that when one quantity increases (days), the other quantity increases (inches of rain).

Step 1: Represent the amount of rain by n.

Step 2: Setup a proportion.

$\frac{15}{14}$ = $\frac{n}{31}$ (where 14 refers to the number of days in 2 weeks)

Step 3: Cross multiply:

15 x 31 = 14n

465 = 14n

Step 4: Find n by dividing both sides by 14.

n = 33.21

Step 5: Round off to the nearest inch.

n = 33 inches
