Suppose the population of a certain city is 3279 thousand. it is expected to decrease to 26668 thousand in 50 years. find the percent decrease

The percent decrease is 713.297%

Step-by-step explanation:

Given:

Initial Population in the city =   3279 thousand

Population in the city after 50 years =  26668 thousand

To Find :

The percent decrease

Solution:

Step 1: Calculate the change (subtract old value from the new value)

Here the Old value is  3279 thousand

New Value is  26668 thousand

Subtracting the old value from new value we get

26668  - 3275  = 23393

Step 2: Divide that change by the old value (you will get a decimal number)

Performing the division

=

= 7.134

Step 3: Convert that to a percentage (by multiplying by 100 and adding a "%" sign)

Converting into percentage

=>

=> 713.297%

1gm = 1000mg so 0.1gm = 1000mg

first, convert the weight to kg

160lb * 1kg/2.2lb = 72.7kg

next, the dose

72.7kg * 100mg/kg = 7270mg

you probably already have the answer but anyways it's b. 15.0
