Question

an electrician can wire on average 4.5 houses in a 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 weeks per month. use y+mx=b

Answer 1

4.5 x 10 = 45

4.5 x 2 = 9

9 + 45 = 54

54 + 4.5 = 58.5

1 + 2 + 10 = 13 weeks

13.5 weeks = 3 months

2 months and 4 weeks
