Jon has to pay a fix-it man $60 to come to his house and $30 per hour after that. how many hours did the fix it man work if jon paid him $390?

Start with $390.

Subtract the fixed fee of $60 for the man to come to the house.

$390 - $60 = $330.

Jon paid $60 just for the man to come to the house. The rest of the money he paid, $330, is to cover the hourly rate.

Divide the $330 by the hourly rate to find the number of hours.

330/30 = 11

11 hours

You can also set up an equation and solve it. Let t = number of hours.

Total cost = fixed fee + hourly fee

total cost = 60 + 30t

We are given a total cost of $390.

390 = 60 + 30t

330 = 30t

t = 11

11 hours

Make an equation for this. Your equation should look like this:

60 + 30h = 390

60 represents the initial fee, and 30h represents 30 dollars per hour.

Solve the equation for h, number of hours the man worked. Subtract 60 from both sides.

30h = 330

Divide both sides by 30.

h = 11

The fix it man worked for 11 hours.

answer: if you weigh 60 pounds on earth, on the moon you will weigh about 10 pounds. if you weigh 120 pounds on earth, you will weigh about 20 pounds on the moon. since weight is caused by the mass of two objects that are near each other, the bigger the objects, the more the force of gravity.

step-by-step explanation: if you weigh 60 pounds on earth, on the moon you will weigh about 10 pounds. if you weigh 120 pounds on earth, you will weigh about 20 pounds on the moon. since weight is caused by the mass of two objects that are near each other, the bigger the objects, the more the force of gravity.
