If you multiply 38.95 by 0.02, you will get the amount taken away from the total when the discount is applied:38.95x0.02=0.78
Then, you subtract that discount price from the total to get the amount Joan pays when she pays with cash:38.95-0.78=38.17
Joan pays $38.17 in cash.
Assuming T, B and N are all on the same line, then we can say
BT + TN = BN
which is the segment addition postulate.
Subtract TN from both sides to get
BT + TN = BN
BT + TN - TN = BN - TN
BT = BN - TN
BN - TN = BT
Which is what choice C is saying. Therefore the answer is choice C.
