Answer:
a 
b 
c 0 customers
Step-by-step explanation:
Given

per customer
Solving (a): Amount (A) on n customers
This is calculated as:



Solving (b): Amount on 134 customers
In this case: n = 134
So:



Solving (c): Customers at noon.
At noon, the amount is 30.
So:

The idea of grouping is to get the terms in groups that allow you to factor out from each group something that becomes a factor in itself, leaving two factors behind that are alike. Like this: rearrange those terms so they are in this order:
(-70y^2 - 63xy) + (90x^3 + 100yx^2). Now out of the first set we are going to factor out a -7y, and out of the second set we are going to factor out a 10x^2. When we do this, this is what we get: -7y(10y + 9x) + 10x^2(9x + 10y). As you can see, what's inside both sets of parenthesis is the same, just in a different order. We can factor that out now, leaving (9x + 10y)(10x^2 - 7y). And that is factored by grouping.
