Question

Tan's electricity bill for the month of August was $267.00. His September bill showed a 2% increase from his August bill. In October, his bill decreased 8% from the amount he was billed in August. How much did Tan spend on electricity over the tree-month period?

Answer 1

267 x 0.02 = 5.34
267 + 5.34 = 272.34

267 x 0.08 = 21.36
267 - 21.36 = 245.64


267 + 272.34 + 245.64 = $784.98
