Maryann and Carlos will have saved the same amount after 2 hours.
Given:
Maryann has $9 saved and can earn $6 per hour babysitting.
Carlos has $3 saved and can earn $9 per hour working at his family’s restaurant.
To find:
After how many hours of work will Maryann and Carlos have saved the same amount?
Solution:
Let Maryan and Carlos will earn the same amount after 'x' hours
Since Maryan has $ 9 already
The amount earned by Maryan after 'x' hours = 9 + 6x
Carlos has $ 3 already
The amount earned by Carlos after 'x' hours = 3 + 9x
As it is assumed that after 'x' hours both earned the same amount
=> 9 + 6x = 3 + 9x
=> 9x - 6x = 9 - 3
=> 3x = 6
=> x = 6/3
=> x = 2
Therefore,
Maryann and Carlos will have saved the same amount after 2 hours.
