An electrician can wire on average 4.5 houses per week. how many months will it take her to wire 55 houses if she wires the same number each week and figures on 4.5 week per month?

It will take 3 months to wire 55 houses. She can wire 18 a month at 4.5 pee week. So you that's roughly 18 a month. 18x3=54 if there is 4 weeks in a month. If you have 5 weeks in the month then it will bend 22 a month. 22x2.5=55 so in this case just 2 and a half months to wire 55 houses at 4.5 houses a week.
