(4) Danny creates up an investment arrangement for friend that will return $5000 the first year, $6125 the second year, $7250 the third year, and so on, for 30 years. State appropriate formulae and determine, how much will the investment yield altogether? (5) If Sandago has a present population of 70,000, and the population is increasing by 3% each year. (a) What will the population be in 10 years? (b) How long will it take for the population to double?
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.
