Just dividing the volumes of the pan, 189 and one bar, 3, suggests that at most she'll be able to cut 63 bars.
But you'll also have to prove that you can divide it in a regular pattern. And you can:
9 divides by 1
10.5 divides by 1.5
2 divides by 2.
So no incomplete bars!
I think the best approach is assuming in percentage. if the cake= 100, then just add the 47 and 23. that would equal 70. then, subtract the 70 from the 100. that would be 30 as your final answer.
« 47+23+?=100 »
« 70+?=100 »
-70 -70
?=30
$3.25 is the other 1/4. So $3.25 x 4 is $13 (their total). They spent $9.75
