Question

The price of a cup of coffee was $2.45 yesterday. Today, the price fell to $2.30. Find the percentage decrease. Round your answer to the nearest tenth of a percent

Answer 1

Based on given conditions, formulate,

`((2.45 - 2.3))/(2.45)`

`= > (0.15)/(2.45)`

Now multiply both numerator and denominator by 100 to make it positive,

`= > (0.15 * 100)/(2.45 * 100)`

`= > (15)/(245)`

Now cross put the common factor,

`= > (3)/(49)`

Now round the number to rhe required place,

`= > (3)/(49)`

`= > 0.1`
