2 answers:
No.
First let's look at how much the sandwiches should cost at a maximum for a total of $20 for 5 sandwiches.
$20/5 = $4 per sandwich. So we can not spend over $4 per sandwich.
If you take the $4.39 and multiple it by the need of 5 sandwiches, you get $21.95.
20 - 21.95 = -$1.95 -> Meaning you are over the budget by $1.95
OR
If you look at $20/$4.39 = 4.56 sandwiches
And 4.56 sandwiches < 5 sandwiches.
No she can't spend $4.39 for each sandwich because if you divide 20 by 5 your quotient will be 4.
