I don't really trust myself to help you as I'm not the greatest with math and I'm also in a rush at the moment. So I'll tag @pooja195 or @mathmate or @Jadeishere :)

Answer 4

Hints:
"Per load" means that the amount is required every time there is an extra load.
Although we don't know the number of loads, we can use x to represent the number.
For example, if it is $5 per load, it costs $10 for two loads, $15 for 3 loads, etc.
How did we get the total amounts, we multiply $5 by the number of loads, which we call x.
So when there are x loads, the cost is 5x dollars.
Service charge means it's a fixed one time amount, which we add to the cost from x loads, irrespective of the number of loads.
So the total cost comes to 5x+15 if there is a service charge of 15 dollars.
