Rashida owns a bike rental company. she charges an initial fee of $10 for each rental and an hourly rate of $4. which of the equations below shows the amount y that rashida charges for a bike rental that lasts x hours?

So, our starting point, at zero hours, you already owe ten dollars. 
So far you know it is +10. 
Now, you multiply for by however many hours you have rented the bike for.
So the equation is:
4x+10.
x= # of hours bike is rented for.
Hope this helps! Have a happy holiday!
