Question

For the second quarter of 2015, Apple sold 61.0 million iPhones. This represented a year- over-year increase of 40%. What were the sales for iPhone for the same quarter in the previous year (rounded to the nearest 10,000)?

Answer 1

It sold 43.57 iPhones for the same quarter in the previous year.

Explanation:

It sold 61.0 million iPhone, which is an increase of 40% over the value of the previous year x.

This can be interpreted as:

61 million is 140% = 1.4 of the previous year amount, that is, x. So

`1.4x = 61`

`x = (61)/(1.4)`

`x = 43.57`

It sold 43.57 iPhones for the same quarter in the previous year.
