Explanation Given: Item costs $600 today and it rises at a rate of 6% per year. Formula used: Formula to determine approximate doubling time; T h a l f = 70 p Where p is rate of increase. Formula to find the exact doubling time; T d o u b l e = log 2 log ( 1 + r ) and new value = initial value × 2 ( t T d o u b l e ) Where r is the growth rate which is equal to p 100 . Calculation: Calculating the approximate doubling time; T h a l f = 70 p ( given rate is 6% ) T h a l f = 70 6 T h a l f = 11.666 Thus, the approximate doubling time is 11.67 years. Calculating the exact doubling time; T d o u b l e = log 2 log ( 1 + r ) ( r is the growth rate r = 0

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 …

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 experime…
