x=4.8
Answer:
5min
Step-by-step explanation:
First form yourself an equation, 113.2-10.8x ≤70
Now begin to work it out
*113.2-10.8(1) ≤70 (instead of x, put a number, this will be how many minutes
1~ 102.4 is not less than or equal to 70, so we repeat this process
2~ 91.9
3~81.1
4~70.3 this is not the answer because even though its at 70 there is still a .3 so we keep going,
5~59.5
59.5 is ≤ 70, so the answer is 5 minutes
P.S. don't believe me? that's okay, use the formula, plug in five to see for yourself
i hope this helps ;)

This is the answer to the problem. All you have to is to combine like terms and you will get the exact same answer.
Answer:
