Let the value of the holiday =x 
then to pay for seven weeks work = 300$ +x
so ,(300+x)/7 * 4 = 30+x
Solve for x :P

anonymous · Answer

think of it as a system of equations
7weeks+1free=300
4weeks+1free=30
no subtract the second from the first to yield
3weeks=270
no solve for the amount one week is worth
1week=270/3=90
no plug 90 back into one of the equations to find what free is worth
4(90)+1free=30
360+1free=30
1free=30-260=-330
that means that instead of getting paid 330 you have to pay 330 for a free day, which means you value a free day at 330
