Answer: help you with what
Step-by-step explanation: you did not ask a question
Umm I can't really explain but like everyone knows that a rectangle had four sides so if each side is multiplied by x then it's going to be that number to the fourth power because you know 4 sides four x's but I not 100% sure just wanted to help out
All you have to do is start by multiplying 485 and 34 (485*34) to find how much he made by just weddings. That should be equal to 16,490. Then you have to multiply 18 by 87 because he charged 18 per copy and there was 87 copies so (18*87). This should now be equal to 1,566. Since you want the total you now should add them which should be 16,490+1,566 and that is equal to 18,056.
