The percentage change is computed by
  percentage change = ((new value)/(original value) - 1) × 100%

Problems 1–3 all use this formula.

1. (3.25/.99 - 1)×100% ≈ 228.3%
2. (2.75/3.25 - 1)×100% ≈ -15.4%
3. (2.75/.99) - 1)×100% ≈ 177.8%

4. The formula for simple interest is
  I = Prt
where P is the principal amount, r is the rate, t is the number of periods, and I is the interest earned. Substitute the given values and solve for t.
  400 = 5000·0.04·t
  400/200 = t = 2

What happens when the two addends have opposite signs and the number with the larger magnitude (size) is positive?
zimovet [89]

Answer:

The smaller addend is subtracted from the bigger addend

Step-by-step explanation:

Represent the two numbers with a and b such that a > b

So, the mathematical representation will be

+a + (-b)

Open the bracket

+a -b

<em>This implies that the smaller addend (b) is subtracted from the bigger addend (b)</em>

<em></em>

<em>Take for instance; a = 6 and b = 4</em>

<em>This gives</em>

<em></em>+6 + (-4)<em></em>

<em></em>

<em>Open the bracket</em>

<em></em>= +6 - 4<em></em>

<em></em>= 2<em></em>
