Question

Ava is saving for a new computer that cost 1,218 dollers .She has already saved half on the money. Ava earns $14.00 per hour .How much hours must Ava work in order to save the rest of the money

Answer 1

Ava has to work 43 and a half (43.5) hours to earn $609.

Explanation:

Given,

Price of new computer = $1218

Solution,

Ava already saved half amount of price of computer.

Half price =
`(1218)/(2) =609`

The amount of money that Eva has to earn is the difference of price of computer and saved money.

Amount to be earn =
`1218-609=609`

Here we use the unitary method to find out the number of hours.

∵ Ava earns $14 in 1 hour.

∴ Ava earns $1 =
`(1)/(14)`

∴ Ava earns $609 =
`(1)/(14)*609=43.5\ hours`

Hence Ava has to work 43 and a half (43.5) hours to earn $609.
