Answer:
6 hours
Step-by-step explanation:
The equation for this would be
c=3h+12
It costs $3 per hour, and there is a $12 cost no matter how many hours the bike is rented for
We know,c, or the cost is $30, so we can substitute that in
30=3h+12
Solve, by isolating the variable,h
First, subtract 12 on both sides
30=3h+12
18=3h
Divide by 3 on both sides
h=6
So, she rented the bike for 6 hours
Well, if you mean 62 tens, then it would be 620, because when you have a number times 10, you just have to add 0 to the end of the number.
