The foreman earned a € on Monday, on Tuesday b € less than €100, on Wednesday half less than on Monday. How many euros did he earn in total? Determine the correct answer expressed in an expression with a variable:

A. a + 100-b+a+a/2
B. a + 100+ b+a-a/2
C. a + 100-b+a-a/2
D. a + 100-b-a + a/2

Correct answer:

x = A

Step-by-step explanation:

$$\begin{gathered} z=a+(100-b)+(a-a/2) \\ z=a+100-b+a+a/2 \\ z=2.5a-b+100 \\ x=A \end{gathered}$$
