Congruent because 2 is a larger number then one and 1 is a smalled number then 2
What you will want to do is replace x with the amount of customers so it would be 42 squared divided by 3025-55x42 which should hopefully give you your answer which is 2.339 but you may have to round it as you can’t have 1/3 of a person etc hope this helps, let me know if I’m wrong
The answer is 1200
3/5=x/2,000
2,000/5=400
3 x 400=1200
