Please help, due today!!​

Answer 1

I have done my math and my calculation from my calculations my answer that I got was 50, I am not positive if it right but it’s worth the try

Answer 2

4h+7
`\leq`20,

Explanation:

Because it says that he has to pay $4 for an hour and we don't know how many hours he will be there so it will 4h, and he just has to pay $7 and we know that he has $20 so he can't have a price that will be higher or equal to 20!

Hope this helps!
