An electrician charges $100 just to come out of your house plus $35 an hour for the actual work. the electrician states that the bill will be at least $240 by the time he finishes.
write and solve an inequality to show the minimum number of hours the electrician will be at your home.
can the electrician work a total of four hours at your house?

100+35x=24

we dont know how many hours he works so we put x next to the 35 because its $35 per hour

for 9 attendees it would cost $18

Step-by-step explanation: First you have to find the unit rate. So for every 7 attendees it costs $14, divide them both by the GCF which is 7. 14÷7=2

7÷7=1

So for every 1 attendee it is $2.

Now to figure out how much it would cost for 9 attendees, figure out what you have to do to 1 to get 9. Multiply it by 9.

And whatever you do to one number you have to do for the other. So $2 • 9 = $18

So for every 9 attendees it costs $18.
