Scrat [10]

Principal clements needs to buy 10 packages

Solution:

Given that, Principal clements wants to buy a pencil for each of the 57 fourth graders in her school

The pencils come in packages of 6

Therefore,

Total number of students = 57

Thus, divide 57 by 6 to get the number of packages clements need to buy

$\text{Number of packages } = \frac{\text{total number of students }}{6}$

Substituting the given values we get,

$\text{Number of packages } = \frac{57}{6} \\\\\text{Number of packages }= 9.5 \approx 10$

Thus principal clements needs to buy 10 packages

An investment made in the stock market decreased at a rate of 1.2% per year for 25 years. What is the current value of the $100,

densk [106]

Use A = P (1 + r/n) ^(nt). Assuming that we're dealing with years here, n = 1, so we have

A = P (1 + r) ^(t), where r is the interest rate as a decimal fraction.

The investment decreases in value, so the common ratio r is (1.000-0.012), or 0.988.

Thus, A = $100,000* (0.988) ^25 = $73947.52 is the current value, after 25 years.
