Calculate the cost of operating a 65 W light bulb continuously for a 30-day month when electrical energy costs \$0.23/kW·h.
\$ 1
How do you calculate cost?
whats the equation?

• physics -

cost= price/kw-hr*timeinHours*powerinKw
=\$.23/kwHr*30days*24hrs/day*.065kw

Alice: These problems are designed for you to invent an equation, think it out, and seek the relationships between time, power, money
