Answer: James has 36 sneakers.

Expression: 3 * 12

Step-by-step explanation:

If James has 3 times as much as Kevin then the amount that he has should equal 3 when divided by 12.

3 = x/12

Multiply 12 on both sides

x = 36

Answer:

c. 3680

Step-by-step explanation:

In 2010, the population was 8000.

In 2014, it increased by 15%.

Population in 2014 :

= 8000 + 15/100×8000

= 8000 + 1200

= 9200.

Now, 2/5 of the population was age 12 or under.

= 2/5 × 9200

= 2×1840

= 3680

Answer - c) 3680
