roy is now 6 years older than julia and half of that amount older than kelly . if in 4 years , roy will be twice as old as julia , then in 4 years what would be roy ’ s age multiplied by kelly ’ s age ?
n0 = 6.0
n1 = 4.0
n2 = 4.0
t0 = n0 / 2.0
t1 = n0 - n1
t2 = n0 + t1
t3 = n1 + t2
t4 = t2 - t0
t5 = n1 + t4
answer = t3 * t5
print(answer)
