QuestionJonathan's computer repair cost \ $336, with \$141 for parts. If labor is \$x per hour for 3 hours, find$ x$.

Studdy Solution

STEP 1

Assumptions1. The total cost of the repair is $336. The cost of the parts is$ p $and is equal to$ 1413. The technician worked for3 hours4. The cost of labor per hour is $x$
5. The total cost is the sum of the cost of parts and the labor cost

STEP 2

First, we need to write an equation that represents the total cost. The total cost is the sum of the cost of the parts and the labor cost.
$Total\, cost = Cost\, of\, parts + Labor\, cost$

STEP 3

We know that the labor cost is the product of the number of hours worked and the cost of labor per hour. So, we can rewrite the labor cost as $3x$ .
$Total\, cost = Cost\, of\, parts +3x$

STEP 4

Now, plug in the given values for the total cost and the cost of parts.
$336 =141 +3x$

STEP 5

Next, we need to solve for $x$ . First, subtract141 from both sides of the equation.
$336 -141 =141 +3x -141$

STEP 6

implify the equation.
$195 =3x$

STEP 7

Finally, divide both sides of the equation by3 to solve for $x$ .
$x =195 /3$

STEP 8

Calculate the value of $x$ .
$x =195 /3 =65$ The cost of labor per hour is $65.

First, we need to write an equation that represents the total cost. The total cost is the sum of the cost of the parts and the labor cost.Total cost=Cost of parts+Labor costTotal\, cost = Cost\, of\, parts + Labor\, costTotalcost=Costofparts+Laborcost

STEP 3

We know that the labor cost is the product of the number of hours worked and the cost of labor per hour. So, we can rewrite the labor cost as 3x3x3x.Total cost=Cost of parts+3xTotal\, cost = Cost\, of\, parts +3xTotalcost=Costofparts+3x

STEP 4

Now, plug in the given values for the total cost and the cost of parts.336=141+3x336 =141 +3x336=141+3x

STEP 5

Next, we need to solve for xxx. First, subtract141 from both sides of the equation.336−141=141+3x−141336 -141 =141 +3x -141336−141=141+3x−141

STEP 6

implify the equation.195=3x195 =3x195=3x

STEP 7

Finally, divide both sides of the equation by3 to solve for xxx.x=195/3x =195 /3x=195/3

STEP 8

Calculate the value of xxx.x=195/3=65x =195 /3 =65x=195/3=65The cost of labor per hour is $65.
