Sara calculates that if she makes a deposit of $8 each month at an APR of 3.6%, then at the end of two years she'll have $194. Lee says that the correct amount is $215. The Regular Deposits Rule of Thumb should be helpful here. What was the total amount deposited (ignoring interest earned)? $ What would the balance be if the total amount were deposited at the beginning of the two years? (Assume no additional deposits are made and the money compounds monthly at an APR of 3.6%) $
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.
