You have to divide your total by 4 to figure out what 1/4 of the price would be. That makes 1/4 of the price $19,631.15 So really you could just do $78,524.60 x2 to figure out the 2x which is $157,049.20 and then do $19,631.15 x3 to figure out the 3/4 amount which is $58,893.45. Then add the two numbers to get $215, 942.65
Step-by-step explanation:
Given that,
DE = 8x - 13
EF = 5x + 17
DF = x + 21
Also,
DE = EF
which means that,
8x - 13 = 5x + 17
8x - 5x = 17 + 13
3x = 30
x = 30/3
x = 10
Now,
DE = 8x - 13 = 8×10 - 13 = 80 - 13 = 67cm
EF = 5x + 17 = 5×10 + 17 = 50 + 17 = 67cm
DF = x + 21 = 10 + 21 = 31cm
They are both equal to below zero
