Answer : -2 +5G
Hopefully this is right
For this case what you should do is solve the problem using for example a rule of three
60% ---> 36
100% ---> x
Clearing x we have:
x = (100/60) * (36) = $ 60
Checking the result:
40% of 60 is
(0.40) * (60) = 24
60-24 = 36 $
Answer:
the original price of the pair of headphones is $ 60
Consecutive integers are 1 apart
they are
x,x+1,x+2
they have a sum of 51
x+x+1+x+2=51
3x+3=51
minus 3 both sides
3x=48
divide both sides by 3
x=16
16+1=17
16+2=18
the numbers are 16,17,18
-5, because when plugging the -1 in for x then multiplying it by 5, you get -5
