Question

When Pico writes articles for an adventure magazine, he gets paid by the word. For a 1,300-word article, he earned $780. How much would Pico earn for a 1,950-word article?

Answer 1

Earning for 1950- word article = $1170

Explanation:

Given that:

Amount paid for 1300 word article = $780

Ratio of words to money = 1300 : 780

Let,

x be the amount for 1950 words.

Ratio of words to money = 1950 : x

As the relationship is proportional

1300 : 780 :: 1950 : x

Product of mean = Product of extreme

780 * 1950 = 1300x

1300x = 1521000

Dividing both sides by 1300

`\frac{1300x}[1300}=(1521000)/(1300)\\x=1170`

Hence,

Earning for 1950- word article = $1170
