3(p-4)  = 3p-4

The distributive property will take the number on the outside and multiply it by everything on the inside.

Example:  7(x-1)  = 7x  -7   because we multiplied the 7 and the x  and we then multiplied 7 and -1.

Use that example to determine what multiple choice answer should be correct!

A video store rents new movies for $5 and older movies for $4. The owner wants
AnnyKZ [126]

Answer:

2480 new movies

Step-by-step explanation:

1) First you need to find out how much money the 400 older movies made.

400*4=1600

2) Next subtract that amount from the amount of revenue that the wants.

14000-1600=12400

3) Divide the amount of leftover money by the amount that a new movie costs to rent

12400/5=2480

This means that in order to reach the desired amount of revenue the store must sell 2480 new movies.

A city's current population is 1,000,000 people. It is growing at a rate of 3.5% per year. The equation P=1,000,000(1.035)^x mod
Sloan [31]
To determine the number of years to reach a certain number of population, we need an equation which would relate population and the number of years. For this problem, we use the given equation:

<span>P=1,000,000(1.035)^x

We substitute the population desired to be reached to the equation and evaluate the value of x.

</span>P=1,000,000(1.035)^x
1400000=1,000,000(1.035)^x
7/5 = 1.035^x
ln 7/5 = ln 1.035^x
x = ln 7/5 / ln 1.035
x = 9.78

Therefore, the number of years needed to reach a population of 1400000 with a starting population of 1000000 would be approximately 10 years.
