Let's pretend those numbers are:
.
We are given the sum is 36: .
One of our numbers is a perfect cube. where is an integer.
The other two numbers are factors of 20. and where .
From here I would just try to find numbers that satisfy the conditions using trial and error.
So I have found a triple that works:
The numbers in ascending order is:
C and f are correct I think
Step-by-step explanation:
x = Iman's money
y = Daphne's money
x = 2y
x - 128 = y - 40
now we use the first equation as identity in the second equation and get
2y - 128 = y - 40
y - 128 = -40
y = $88
x = 2y = $176
these were the starting values.
now, after spending, they have both left
176 - 128 = 88 - 40 = $48
