He plans on buying katie 4 dozen roses and 6 chocolate bars.Each dozen of roses cost $15 and each chocolate bar cost $1 each.How many hours does he have to work until he gets the amount he needs?

Answer 1

Hi Katie,

 

The question is a little confusing . . . we're not sure if it asks for the total number of hours of the number of additional hours??

 

Step one is to figure out how much money he needs . . .

 

4 dozen roses at $15 each = $60

 

6 chocolate bars at $1 each = $6

 

total = $66

 

Jorge already has $33 so he needs $33 more

 

He charges $3 per hour.  33 / 3 = 11 additional hours of babysitting

 

He already earned $33 which means he already worked 11 hours for a total of 22 hours.

 

Enjoy homecoming.

Answer 2

1 doz = $15

4 doz = $60

 

1 bar = $1

6 bar = $6

 

He needs $66. He has $33. So he has to make $33. At $3/hour that is 11 hour.
