Acensus showed that from 1990 to 2000, a country’s population increased by 25.3%. the country reported its population in 2000 to be 15,264,465. what was the country’s population in 1990?

12,182,334

Step-by-step explanation:

If some quantity q increases by r%, then the increment will be . The new quantity Q (increased) will be

If we know the final quantity, we can know the original q as

The census showed the rate of increase of the population was r=25.3% and the final population in 2000 was Q=15,264,465. So we can know the population back in 1990 was

6,250

step-by-step explanation:

to get the area, multiply 360 by 160.(57,600)

to find out how many bags of fertilizer it will take, first figure out how many square feet one bag can hold. divide 1000 by 8(125) to get the unit rate(how many square feet one pound of fertilizer can hold)and multiply it by 50(6250). if i haven't made a mistake, that is the answer.
