There are n pennies in a jar. Let p represent the decimal ratio of the pennies that are dated before 1983. Which of the following equations repesents the number of pennies that are dated 1983 or later?
The proportion of pennies before 1983 would be np. Therefore, the pennies dated 1983 or later would be n(1-p).
The proportion of pennies before 1983 would be np. Therefore, the pennies dated 1983 or later would be n(1-p).

This is a percentage problem, so it is important to know that 40% of some value is equal to 0.4 of said value. So to find 40% of $40, we multiply 40 * 0.40, which equals 16. This 16 represents 40% of the original value of $40. So if a student was to spend 40% less than they usually spend, we would subtract $16, which is 40% of the original value, from $40, giving us an answer of $24.
