What problem a slove with fraction 2 3/4 will be greater than?
Answer =$388.75
25x.10= $2.50, 35x.15=$5.25, 350x.20=$70
$2.50+5.25+70=$77.75x5 days=$388.75
For this case we have the following inequality:

We must clear "y", so, we have the following steps:
1st step:
Apply distributive property to the right side of the inequality:

2nd step:
We add similar terms:


3rd step:
We add 48 to both sides of the equation:

4th step:
We divide between 22 on both sides:

Thus, the result is given by:
