Given:
She earns $14 dollar per hour at grocery
She earns $18 per hour walking dogs
Required:
to earn at least 320$ per week she work less than 25 hours
Step-by-step explanation:
Let x be the work at grocery
Let y be the work at walking dogs so
5x+14y>320
We have to find the way in which she can earn at least 320$ and work less then 25 hours
so in this equation she can work less than 25 hours or earn more money
Required answer:
5x+14y>320
