Answer:
Ava has to work 43 and a half (43.5) hours to earn $609.
Step-by-step explanation:
Given,
Price of new computer = $1218
Solution,
Ava already saved half amount of price of computer.
Half price = [tex]\frac{1218}{2} =609[/tex]
The amount of money that Eva has to earn is the difference of price of computer and saved money.
Amount to be earn = [tex]1218-609=609[/tex]
Here we use the unitary method to find out the number of hours.
∵ Ava earns $14 in 1 hour.
∴ Ava earns $1 = [tex]\frac{1}{14}[/tex]
∴ Ava earns $609 =[tex]\frac{1}{14}\times609=43.5\ hours[/tex]
Hence Ava has to work 43 and a half (43.5) hours to earn $609.
