15 pizzas would cost $180.
$28.75 an hour.
If she worked $25 an hour, then got a raise of 15%...It turns into $28.75.
To get the days income, you simply multiply the rate by the time. $28.75 times 8 to get $230.
Hope this helps!

You would use less than or equal to if your inequality can be equal to a number. Here's an example.

x + y (equal to or less than) 45
John needs to buy X oranges and Y apples. He CANNOT buy more than 10 total fruits.
