Question

In 2012, the population increases by 15%. Write an expression, using only multiplication, that represents the deer population in 2012.

A) 650 + 0.15 X 650
B) 650 - 0.15 X 650
C) 650 X 1.15
D) 650 / 1.15

Answer 1

The correct expression to represent the population after a 15% increase is 650 × 1.15, showing the original population plus the 15% increase.

Step-by-step explanation:

The expression that represents the deer population in 2012 after a 15% increase is given by taking the original population and adding 15% of its value. This increase can be calculated by multiplying the original population by 1.15. Therefore, the correct expression would be:

650 × 1.15

This means you take the population of 650 deer and increase it by 15%, which means you're effectively getting 100% of the original population (the 650 deer) plus the additional 15%. When you multiply 650 by 1.15, you're combining these two percentages, giving you the total population after the increase.
