The cost of electricity is $.08 for each of the first 300 kWh and $.13 for each kwh over 300 kwh. Find the number of Kilowhatt-hours used by a family that receives a $51.95 electric bill.
-----
cost = 0.08a + 0.13b
---
51.95 = 0.08*300 + 0.13b
51.95 = 24.00 + 0.13b
0.13b = 27.95
b = 215 hrs
---
Total hours = 215+300 = 515
