This is a linear programming question
if u want to solve the question, u can plot a graph(see the picture)
while x is n, y is r
and u may find out all of the integral values of x ,y in the required region, and sub them to 6450x+7150y=c, where c is the overall customers number, see which point give u the largest number of customers, u may get the ans then

Answer:
________
Step-by-step explanation:
Given
Line up the numbers
Multiply the top number by the bottom number one digit at a time starting with the ones digit left(from right to left right)
Multiply the top number by the bolded digit of the bottom number
Multiply the bold numbers: 1×4=4
Multiply the bold numbers: 2×4=8
Multiply the top number by the bolded digit of the bottom number
Multiply the bold numbers: 1×1=1
Multiply the bold numbers: 2×1=2
Add the rows to get the answer. For simplicity, fill in trailing zeros.
adding portion
Add the digits of the right-most column: 4+0=4
Add the digits of the right-most column: 8+1=9
Add the digits of the right-most column: 0+2=2
Therefore,
________
