How long will it take for me to get to $250?

im working with my dad cleaning apartments and i get paid $5/ hr. i average working 2-3 days a week. i usually earn about 15-20 bucks per day (3-4 hrs). I have eraned $100 bucks in only half of june, but i put 50 bucks into my savings account. so i have $50 and already have $40 for my july paycheck. should i have somewhere near $200-250 near the end of july if i stay ontrack?
