If N.E.P.A. charges 65 kobo per kilowatt-hour for electricity supplied to consumers, what bill would an electric iron rated at 750 watts attract when used for 24 hours?

65kobo=1kw/h=1000*60*60
65kobo=3600000
X= 750*24*60*60
X= 64800000
Cross multiply, we have that 3600000X is equal to 64800000*65

3600000X =4212000000
X= 4212000000 /3600000
X =1170 naira.
Convert from naira to kobo
100k= 1naira
1170=x
100x=1170
Divide through by 100.
= 11.70
