The phrase “inequality” tells you that you will be using inequality signs, greater than, less than, greater than or equal to, or less than or equal to. Those signs look like this (not ordered) ≤ ≥ < >
So now we have to consider the speed limit 25mph, and remember s is used to represent how fast you are going. We can start be setting up 25_s and now we must determine what sign to use. Does it make sense to go faster than the speed limit? No it doesn’t, it’s a limit. what about equal to, does it make sense to go at the speed limit? Yes you can travel 25mph in a 25mph zone. So your speed will be less than or equal to 25, because you know you can’t go faster than that but you can travel at that number. So it looks like:
25 ≥ s.
If you need help understanding why I used that particular inequality sign message me for help.
The expression would be 13^2 + 6^3
if it needs to be simplified further just plug that into a calculator

Step-by-step explanation:
Given
Tom and Martin both worked 9 hours this week and sold $360 worth of meals
Tom's percent of tips was 15% while Martin's was 20%
Find out the most money this week between Tom and Martin
To proof
In this question take two cases
FIRST CASE
Martin worked 9 hours
sold worth of meals = $360
Martin's percent of tip = 20%
First convert 20% in decimal form
=
= 0.20
than the equation becomes
Martin makes money = 9 × 2.50 + 0.20 × 360
= 22.5 + 72
= $ 94.5
SECOND CASE
Tom worked 9 hours
Tom's percent of tips = 15%
sold worth of meals = $360
First 15 % is written in decimal form
=
= 0.15
than the equation becomes
Tom makes money = 9 × 2.15 + 0 .15× 360
= 19.35 + 54
= $ 73.35
Thus martin makes money is $94.5
Thus tom makes money is $73.35
Hence Martin makes more money than tom
Hence proved
