Answer:

210 people

Step-by-step explanation:

We can use proportions to solve.  We will put the percent over the number of people

5%           35%

--------- = ----------

30            x

Change the percent to decimal form

.05          .35

--------- = ----------

30            x

Using cross products

.05x = .35 *30

Divide by .05 on each side

.05/.05 x = .35 * 30/.05

x = 210

Answer:

  • Part A = 600
  • Part B =210

Step-by-step explanation:

Find the Population

  • 5% of a population = 30
  • Let the population = x
  • (5/100) x = 30                       Multiply by 100
  • 5x = 3000                             Divide by 5
  • 5x/5 = 3000/5                      Do the division
  • x = 600

==================

Find 35% (y) of the Population

  • 35% of x = y                   Find 35% of 600 Where y is the value of 35%  of 600
  • 35/100 * 600 = y           Multiply 35 * 600  
  • 21000/100 = y               Divide by 100
  • 210 = y
