If salad costs $8, and soup costs $5, determine Janet's consumer equilibrium with a budget of $20. Confirm this is the correct answer using the MUx/Px=MUy/Py formula (or show that the answer is very close to equal). If the formula is not completely true, explain why.

I've found the utils for both the soup and salad, I just don't know how to find the choices and the consumer equilibrium.

Soup	Marginal utility	Mu/P ($5)	Salad	Marginal utility	Mu/P ($8)
1	10	10/5= 2 utils	1	9	9/8=1.1 utils
2	8	8/5=1.6 utils	2	7	7/8=0.88 utils
3	4	4/5= 0.8 utils	3	5	5/8=0.63 utils
4	2	2/5= 0.4 utils	4	4	4/8=0.5 utils
