You decide to get an estimate on the cost of repairs for the green food truck.
the mechanic explains that the cost of the repairs comes out to be about
$9,500. this price includes the cost of labor and the cost of the parts needed
to do the repairs. if labor costs are 3/5 the cost of the parts, how much
would you save by doing the repairs yourself and just purchasing the parts?

asap !

  $3562.50

Step-by-step explanation:

If the cost ratio is ...

  labor : parts = 3/5 : 1 = 3 : 5

then the ratio of labor to the whole cost is ...

  labor : total = 3 : (3+5) = 3 : 8

The amount saved by not paying for labor is ...

  (3/8) × $9500 = $3562.50 . . . labor charge

t = 3

step-by-step explanation:

put t = 3 in this expression :

(3²-1)(3²-2)(3² - 3)(3² - 4) = 8×7×6×5 = 56×30 = 1680

answer: 0

step-by-step explanation: the positive, like 5, + its opposite, like -5 would be 0

5+(-5)=0, or 5-5=0
