Traditionally, jewelers advise men to spend two months’ salary on an engagement ring for their fiancée. Arnie is shopping for a ring for Sasha, his bride-to-be. If Arnie’s annual salary is $30,000 and he follows the tradition, how much will he spend on Sasha’s engagement ring?

$5,000

Explanation:

If  Arnie has an annual salary, that sum may be divided by 12 (the number of months in a calendar year) to get his monthly income.

The amount so determined is then multiplied by 2 if he is to follow the tradition on how much is to be spent on engagement ring.

Thus,

Arnie's monthly salary = ($30,000/12)

= $2,500

To follow tradition, amount to be spent on engagement ring

= $2,500 × 2

= $5,000
