Question
The number of employees in Jorge's business can be modeled by the equation E(t) = 4(1.2)t, where t is the number of years since the business opened. Which of the following is the best interpretation of the number 4 in this context?
- The increase in the number of employees each year
- The number of years the business has been open
- The number of employees when the business opened
- The percent increase in the number of employees each year
The correct answer is: The number of employees when the business opened
According to exponential formula
Y = a(b) x
Where a = initial value
Hence option (c).

The histogram summarizes the distribution of the total annual precipitation, in inches, for the city of Seattle for 68 years. The first bar shows the number of years with total annual precipitation of at least 20 inches but less than 25 inches, the second bar shows the number of years with total annual precipitation of at least 25 inches but less than 30 inches, and so on.
How many years had at least 50 inches of total annual precipitation?
