This might not be super helpful but it’s either 50 or 130. Sorry i haven’t done this for a while!!
Sadie= 82
Buddy= 54
Divide by 2, 136/2=68, then rest 14 to one half, 68-14=54, next add the other half 14, 68+14=82.
There you have it, i hope it helps you
F = 1.8C + 32
F = 1.8(100) + 32
F = 180 + 32
