Recall the compound interest formula

Where r = 0.04, n = 12 since compounded monthly, t = 30, and p, initial value, is 24000.
Plug them in, 79523.95 seems to be the solution.
Xy is the number
A) x + y = 7
B) 10y + x = 10x + y + 9
collecting terms of equation B
B) -9x + 9y = 9
multiplying A) by 9
A) 9x + 9y = 63 then adding it to equation B)
B) -9x + 9y = 9
18y = 72
y = 4
x = 3
The number is 34
