Question 2. Two competing companies produce mobile phones. Company A starts production
at 1000 phones per week and plans to increase output by 200 each week. Company B starts
production with 500 phones per week and plans to inerease output by 20% each week.
a. Caleulate the weekly production in weeks 1; 5; 10; 15. Estimate the week in which the output
is the same for both firms.
b. Calculate the total production during the first 15 weeks for each firm.
Question 3. Heating a large buuilding requires 50, 000 gallons of oil in 2013. As the building is
extended, two forecasts for growth in demand for oil are made:
Forecast 1: inereases of 5000 gallons per year.
Forecast 2: inereases of 6% each year.
Use series to calculate for each forecast:
a. The number of gallons required in 2015, 2020.
b. The total consumption of oil from 2015 to 2020 inclusive.
