Answer:c
Step-by-step explanation:
You can find the answer by adding the two packages and subtracting them by 5.
2 1/2+2 3/5=5 1/10
5 1/10-5=1/10
Yolonda will have 1/10 left over.
The exponent only applies to the x not the 4
so only the x has permission to move to the denominator
this leaves you with 4/x^3
