Question

there are 500,000 bacteria at the end of a pin point. 1000 bacteria can make a person sick. then bacteria at the tip of a pin point can make 500 people sick. Also, many people do not know that bacteria can (reproduce). Let's say there are 5 bacteria and we leave it for 15 minutes. bacteria will multiply to 10. if left for up to 30 minutes, 20 bacteria will form. if left up to 45 minutes. bacteria will multiply up to 40. every 15 minutes the bacteria will double 2. if you start with five bacteria that reproduce every 15 minutes, how manu bacteria would you have after 12 hours ?

If the bacteria double every 15 minutes, we can calculate the number of bacteria after 12 hours (720 minutes) by dividing the total time by the doubling time. Doubling time = 15 minutes Total time = 12 hours = 720 minutes Number of doubling periods = Total time / Doubling time Number of doubling periods = 720 minutes / 15 minutes = 48 doubling periods Now, if you start with 5 bacteria and they double 48 times, you can calculate the total number of bacteria using the formula: Final number of bacteria = Initial number of bacteria * (2^Number of doubling periods) Final number of bacteria = 5 * (2^48) Calculating this, we get: Final number of bacteria = 1,407,374,883,553,280 So, after 12 hours, starting with 5 bacteria that double every 15 minutes, you would have 1,407,374,883,553,280 bacteria.

The Humane Society has asked for our help again this week. Currently they are charging $50 for an adoption fee. Unfortunately they just pulled this number out of the air and do not know why they are charging this amount. They would like to charge an amount that covers all the adoption costs – both the variable costs for adoptions as well as the fixed cost for the kennel portion of the Humane Shelter operations. We can help them by doing a breakeven analysis. During a client meeting we gathered these facts. There are 2 part-time employees that each earn $1000 per month. The utilities for the kennel area (water, electricity) are $200 per month. The average food cost for animals in the kennel is $800 per month. In addition, each animal that is adopted receives a rabies vaccination that costs $4 and is micro-chipped that costs $6. At the current cost of $50, how many animals must be adopted to break-even? What would break-even be at a $60 adoption fee? What would break-even be if the fee were lowered to $40? The newspaper has suggested that the Humane Society advertise to increase pet adoptions. The package that they have recommended costs $1000 for a very small ad run every day for a month. If the Humane Society does this extra advertising, how will it affect breakeven? Based on what you have learned about elasticity, what price do you recommend for the adoption fee?
