the number of cell phone subscribers in a certain country in the early 2000s was projected to follow the equation, N(t) = 40t + 67 million subscribers, in year t (t = 0 represents 2000). The average annual revenue per cell phone user was $350 in 2000. assuming that, because of competition, the revenue per cell phone user decreases continuously at an annual rate of 10%, give a formula for the annual revenue in year t. what would be R(t)? = using R(t) as an estimate of the rate of change of total revenue, estimate the total revenue from 2000 into the indefinite future.
Unitary Method
The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products.
Speed, Time, and Distance
Imagine you and 3 of your friends are planning to go to the playground at 6 in the evening. Your house is one mile away from the playground and one of your friends named Jim must start at 5 pm to reach the playground by walk. The other two friends are 3 miles away.
Profit and Loss
The amount earned or lost on the sale of one or more items is referred to as the profit or loss on that item.
Units and Measurements
Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experiments to set up the devices.
