Floods

After the floods that hit a school, parents help repair the damage. My father worked at the school 50 hours, my mom 5 hours less. How many hours worked, mother? How many hours worked my parents together?

Correct answer:

m =  45 h
x =  95 h

Step-by-step explanation:

$m=50-5=45\text{h}$

$x=50+m=50+45=95\text{h}$
