A.12.6m
C.1.05m
B.12.05m
D.0.6m

Answer 1

Answer: C.1.05m

Step-by-step explanation:

If Jason earns $m$ dollars monthly and then this salary is increased by $5\%$, we can write it as follows:

$m+5\%m$ (1)

Since $5\%=\frac{5}{100}=0.05$, expression (1) is:

$m+0.05m$ (2)

Solving:

$1.05 m$This is Jason's new salary

Hence, the correct option is C
