A town in east Texas received 15 inches of rain in two weeks. If it kept raining at this rate for a 31−day month, how much rain
blsea [12.9K]

Answer:

33 inches

Step-by-step explanation:

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

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
