Answer:The sitting fee is 15 dollars
Step-by-step explanation:If you were to use the formula y=mx+b then the starting equation would be y=12x+b. It already gave you the cost for the amount of photos respectively so 51=12(3)+b. 12 times 3 equals 36 and 51 minus 36 equals 15. The same way would be used for 87 dollars and 123 dollars while using the amount of photos respectively. 87=12(6)+b. 12 times 6 equals 72. 72 plus 15 equals 87. 123=12(9)+b. 12 times 9 equals 108. 108 plus 15 equals 123. Therefore the sitting fee is 15. (51=12(3)+15, 87=12(6)+15, 123=12(9)+15)
Since it's a local (a possible branch) hardware store, it's POSSIBLE BUT VERY UNLIKELY:
PROOF: Assume 100 clients/day are buying from this store, that means,
3,600 customer a month or 43,200 clients a year. The one-millionth customer will occur after 1,000,000/43,200 = 23 years. or it will be after 46 years if the average customer is 50/day. So it is possible but MOST UNLIKELY
