Here is the background information:

Here is the background information:
A consumer spends her income on nuts (n) and fruits (f) both of which are measured in units in pounds. THe total utility is shown below:

#of units consumed TU(n) TU(f)
0 0 0
1 64 32
2 96 48
3 112 56
she has a budget of $12 and P(n)= $2, and P(f) = $1
Question: Would Q(n) = 5 and Q(f = 2 be utility maximizing? Explain not in reference to TU but MU or marginal utility

I said yes, because the marginal utility for both n and f is the same (I used the marginal utility rule), but I don’t know if that is correct, help?
