You would have to set the equation to the profit Jennifer got, which you know to be 63 dollars:
63=0.5e-5
To begin solving for e, which represents the number of erasers sold, add five to each side to get e alone.
68=0.5e
Multiply each side by two to get a whole x value on the right side
136=e
Jennifer sold 136 erasers
B 24 I the answer to your question
Through a geometric proof, 2(55x-1) = 107x+1
110x-2=107x+1
3x=3
x=1
