Answer: B equals 157,5 - ((157,5 * 1,1) - 157,5) = 157,5 - 15,75 = 141,75.
Step-by-step explanation:
B is 10% less than C.
C is 5 % more than 150.
C is 150 * 1,05 = 157,5
Then B is (150 * 1,05) - 10%. Which can be calculated the long way as follow; 157,5 - ((157,5 * 1,1) - 157,5) = 157,5 - 15,75 = 141,75.
