The population of Boomtown is currently 3000 and expected to grow by 4.7% over the next year. What will its population be by then?

The population of Dullsville, on the other hand, is currently 2000 and expected to decrease by 3.3% over the next year. What will its population be by then?

Population of Boomtown in next year = 3141

Population of Dullsville in next year = 2066

Step-by-step explanation:

i) Given: Current population of Boomtown is = 3000

growth rate = 4.7% = 0.047 [in decimal]

Growth in population in 1 year=  (growth rate) x (Current population)

= 0.047 ×  3000 =141

Population in next year = Current population + Growth in population in 1 year

=  3000 + 141 = 3141

Hence, population of Boomtown in next year = 3141

ii) Given: Current population of Dullsville is = 2000

growth rate = 3.3% = 0.033 [in decimal]

Growth in population in 1 year=  (growth rate) x (Current population)

= 0.033 ×  2000 =66

Population in next year = Current population + Growth in population in 1 year

=  2000 + 66= 2066

Hence, population of Dullsville in next year = 2066

answer:

it will cost 480 dollars to refurbish the larger wood floor

step-by-step explanation:

as it's a ratio of 4 that costs 384 dollars, divide the price by the ratio

384 / 4 = 96 dollars

96 dollars per unit of the ratio

now to get the price to refurbish the larger wood floor, times the price by the units

96 * 5 = 480
