Please help me with this, it’s due in an hour
Elena-2011 [213]
#3. For each hour worked, the employee makes $15/hour. This is true for every hour he works, so if he works for 4 hours he will make $60.

#4. For every second, the hot air balloon increases height by 5 feet.

#5. X&Y are proportional because for every hour, 5 feet are gained. Thus, after 7 hours, 35 feet are gained.

Thats all i have time to do right now. Good luck :)
