You can rent time on computers at the local copy center for a $6 setup charge and an additional $5.50 for every 10 minutes. how much time can be rented for $21?

If 10 minutes block, then it can be rented for 20 minutes. If no blocks, then 27.27 minutes

Step-by-step explanation:

Initial setup cost is $6.

Every 10 minutes, $5.5 is charges, so each minute   is charged.

Let time used be t, so we can set up an equation as:

21 = 6 + 0.55t

Where t is in minutes

we solve for t to find out how many minutes we can rent for $21:

since it is charged PER 10 MINUTES, so we can rent it for 10, 20 , 30 minutes etc.

WE CANNOT RENT FOR 30 minutes as we dont have enough money (only for fractional amount of a little over 27 minutes). Thus, we will have to have some money left over and rent for 20 minutes.

understand that i don't know the answers

will someone answer his question

.there can be infinite values of m and n that can satisfy the above equation. for each value of m of m or n. there maybe infinite sets of solution for the above
