Kendra has a babysitting business that she earns $6 per hour she babysits. She already has $50. She wants to earn enough to buy a new phone for $350. Write an equation that represents how many hours she needs to babysit to earn the money to pay for the phone. How many hours does she have to work?

50 hours

Explanation:

Let x represents the number of hours that Kendra needs to work

She gets $6 for one hour so for x hours

6x

She already have $50 so add it  

6x + 50

She wants to have a total of $350 so equation becomes

6x + 50 = 350

Now lets solve this equation

6x = 350 - 50

6x = 300

x = 300/6

x = 50 hours

So Kendra have to babysit for 50 hours so that she can buy a new phone for $350
