Amount calculation

Since Georgia is a coffee enthusiast and drinks three coffee drinks a day from a local coffee shop costing $1.25 each, and being concerned with the expense of her coffee habit Georgia looks into making her own manual brewed coffee, and a bag of premium coffee beans costs $70.00, a coffee grinder costs $120.00, and the manual coffee brewer costs $40.00, to determine, if a bag of coffee makes enough for 100 cups, how many full bags of coffee does she need to consume before saving money, the following calculation must be performed:

  • 70 x 1 + 120 + 40 = 230 / 100 = 2.3
  • 70 x 2 + 120 + 40 = 300 / 200 = 1.5
  • 70 x 3 + 120 + 40 = 370 / 300 = 1.23

Therefore, she needs to consume 3 full bags of coffee before saving money.
