A. A plumber charges $65 for a diagnostic check. After the check, it is $85 per hour for the work. Write an equation to model this sitaution.

B. Using the equation, how many hourscan you afford if you have $320?

A. 65 + 85x = total cost

B. He can afford 3.035 hours, or 3 if he has to pay for complete hours.

Step-by-step explanation:

A. Let's set up our equation. The flat rate is 65, so

     65 +

   The continuous rate is 85/hr, so with x representing hours

     65 + 85x

   All this added together will equal the total cost, so

     65 + 85x = total cost

B. Let's plug in $320 for our total cost.

     65 + 85x = total cost

     65 + 85x = 320

    Simplify and solve for x. First subtract 65 from both sides.

     85x = 320 - 65

     85x = 258

     x = 258/85 = 3.035 hours

the camry sales+accord sale=828,000. to make it so the two numbers are 18 thousand apart and still equal 828,000, you first need to find out what half of 828,000 is. 828,000/2=414,000. for the two numbers to equal 828,000, you have to add the same amount as you subtract from the middle. in this case, the number is 9,000 because it's half of 18,000. to equal 828,000, you have to add 9,000 to 414,000 for the camry and subtract 9,000 from 414,000 for the accord. 414,000+9,000=423,000.

414,000-9,000=405,000.

423,000+405,000=828,000.

423,000-405,000=18,
