1. Power to a power rule (you multiply the power outside the parentheses by the power of each term in the parenteses)

2. Quotient rule of powers (you have the same base, you extract exponents when dividing)

3. Simplify powers (self explanatory)

480 pennies dated after 2000.

Step-by-step explanation:

1. Pennies dated before 1980 (x) - 25%,

All pennies (1,200) - 100%.

Then

$\dfrac{x}{1,200}=\dfrac{25}{100},\\ \\100x=25\cdot 1,200,\\ \\x=25\cdot 12=300.$

2. Pennies dated from 1980 to 2000 (y) - 35%,

All pennies (1,200) - 100%.

Then

$\dfrac{y}{1,200}=\dfrac{35}{100},\\ \\100y=35\cdot 1,200,\\ \\y=35\cdot 12=420.$

3. Rest pennies are dated after 2000, then

1,200-300-420=480.
