1 + 4 = 5, in this question, there is 1 "4", and 1 + 4 = 5
2 + 5 = 12, in this question, there are 2 "5", and 2 + 5 + 5 = 12
3 + 6 = 21, in this question, there are 3 "6", and 3 + 6 + 6 + 6 = 21
So for 5 + 8, there are 5 "8", so:
5 + 8 + 8 + 8 + 8 + 8 = 45
45 is your answer
hope this helps
Jack's current monthly bill is
(1200 kWh +400 kWh)*($0.075/kWh) = $120
On the interval use plan, Jack's monthly bill would be
(1200 kWh)*($0.03/kWh) + (400 kWh)*($0.15/kWh) = $36 + 60 = $96
If Jack were to switch, his savings would be $120 -96 = $24.
The appropriate choice is ...
b. Jack should switch to the interval use plan, which would save him $24 per month.
