$4 b+5-5 = t-5$

After simplification $4 b=t-5$

Dividing '4' on both sides , we get and simplification

$b = \frac{t-5}{4}$

now Final answer $b=\frac{t-5}{4}$

I would say it is A because if you subtract p, the original price by $2.50, you would get d, the discounted price. Look at B u see that you're adding the discount which doesn't make sense. Looking at C, the discounted price of different prices can't always be the same. And finally, D, the discounted price is greater than the original. Also, if you subtract you would get different discounts.
