Answer:
10 hour rental
Step-by-step explanation:
Let x = number of hours
HD cost: 7x + 65
L cost: 4x + 95
Set the two cost expressions equal and solve for x, the number of hours.
7x + 65 = 4x = 95
3x = 30
x = 10
The costs are equal for a 10 hour rental.

Answer:
$12.49
Step-by-step explanation:
The price right now = 0.8 * the original price
9.99 = 0.8*x
x=12.4875
x≈12.49
Sorry, I thought your problem meant that it was 20% the original price, not 20% off.
So its going to equal a fraction.
To convert let x equal the repeating decimal (0.1515... it would usually have a line on top of it but I cant type it)
Then examine the number see what place it is in then add another place (in this case it is in the 10000ths place) so multiply it but 10000x
so it would look like: 10000x = 0.1515
then you will move the decimal in to a whole numbers place (0.1515 to 1515.1515
then subtract the decimal 1515.1515- .1515= 1515.
dont forget to subtract from both sides so subtract the 10000x too. (999.515)
then write as fraction form 1515/9999
