Answer:
430
Step-by-step explanation:
100+(110×3)=430
100 is on his first house
4 houses -the man is already taxed 100 for the first house.
we are trying to find 4 houses,as we already know the first house we have 3 left.so you do 110 times 3 to find the three houses and add the amount taxed of the first house=to work out 4 houses.
simple:first house tax already given now work out remaing 4(mentions addition each house is taxed 110 so multiply by 3 and add it together with the first house)

Step-by-step explanation:
