Answer:
( t - p ) / 85x = h
( t - 265.95 ) / 85x = h
648.45 - 265.95 / 85x = 3.32h
h = 3.32
Therefore ( t - p ) / 85x = 3.32
Step-by-step explanation:
648.45 - 265.95
282.50 /85
= 3.32 hrs
Finding equation to find hours can be shown as
( t - p ) / 85x = 3.32
How we found equation to find total
Parts = 19 x 14 - 5/100 = 266- 0.05
648.45 - 265.95 = 282.5
282.5/85 = 3.323 near to 3,233529
Labour = 85x = 17 (5 + x)
Equation = 17(5+ x) + 14(19) - 5/100 = 648.45 where x = 85
Equation = ( 85x x 3 1/3) + 265 - 19/20 = t
The repair bill is an illustration of a linear equation. The equation that represents the scenario is: [tex]648.45= 265.95+ 85\times x[/tex]
And the solution (i.e. number of hours) is: 4.5 hours
Given that:
[tex]Bill = 648.45[/tex]
[tex]Parts = 265.95[/tex]
[tex]Labour = \$85[/tex] per hour
Let the number of hours spent be x
So, the equation is:
[tex]Bill = Parts + Labour \times x[/tex]
This gives;
[tex]648.45= 265.95+ 85\times x[/tex]
Collect like terms
[tex]648.45-265.95= 85\times x[/tex]
[tex]382.5= 85\times x[/tex]
Divide both sides by 85
[tex]4.5 =x[/tex]
[tex]x = 4.5[/tex]
Hence, the equation is:
[tex]648.45= 265.95+ 85\times x[/tex]
And the solution (i.e. number of hours) is: 4.5 hours
