Question

If 5% = 30 how many people = 35%

Answer 1

• Part A = 600
• Part B =210

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

Answer 2

210 people

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
