Peppy Pets charges a flat fee of $15 plus $3 per hour to keep a dog during the day. Happy Hounds charges a flat fee of $21 plus
stich3 [128]

Answer: d) 3 hours.

Step-by-step explanation:

Let x be the required number of hours for which the total fee charged by the companies the same.

Given: Peppy Pets charges a flat fee of $15 plus $3 per hour .

So Total charge = 15+3x  ( in dollars)

Happy Hounds charges a flat fee of $21 plus $1 per hour.

So Total charge = 21+x  ( in dollars)

When the total charge for both companies are the same, then

15+3x=21+x\\\\\Rightarrow\ 3x-x=21-15\\\\\Rightarrow\ 2x=6\\\\\Rightarrow\ x=3

Hence, the correct option is d) 3 hours.

Claire earns $8.50 per hour babysitting plus a $15 travel fee. Brooklyn earns $9.50 per hour walking dogs plus a $5 supply fee.
ANTONII [103]

Answer:

I believe Claire makes $24.50 and Brooklyn makes $14.50, so if you wanted to make Brooklyn walk an extra hour, she would have 24.00 adding the supply fee which is $5 which would make it $29.00.

Now i am going to try to actually solve it

8.50x15=127.5

9.50x5=47.5

9.50x13=123.5

this is so wrong i am so sorry, i just hope this helps you understand your question a bit more!
