A man is taxed N100 on the first house he owns. For each additional
house he owns, he pays #110 tax.
How much tax will he pay on 4
houses?

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)

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500
