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?

Respuesta :

Answer:

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
