The bill before the incentive was $ 145

Solution:

Let the actual bill be of Rs ‘a’

A book store is offering 10% off our total bill

\text { Discount on bill }=\frac{10}{100} \times a

So, new bill amount to be paid = original amount – discount

\begin{array}{l}{130.50=a-\frac{10}{100} \times a} \\\\ {130.50=\frac{100 a-10 a}{100}} \\\\ {13050=900} \\\\ {a=\frac{13050}{90}} \\\\ {a=145}\end{array}

So, the original bill was of $145 Thus Option B is correct
