the price of a smartphone was increased by 8% in the first year next year was decreased by 5% find the final price of the smartphone if initially the price was 18000

8% of 18,000 = 1,440

18,000 + 1,440 = 19,440

5% of 19,440 = 972

19,440 - 972 = 18,468

The final price is 18,468.

Answer: d. 39 cmin the diagram, the approximate length of the minor arc de is 39 centimetres.step-by-step explanation: the formula for the length of an arc in a circle is as displayed below.let the length of the minor arc de = xx = 2( pi )r × angle of sector / 360°from this, we will substitute the values given from the problem into the formula to obtain the length of the minor arc de.x = 2( pi )r × angle of sector / 360°r = radius = 25cmpi as an approximate value = 3.14angle of sector = 120°x = 2( 3.14 )( 25 ) × 120° / 360°x = 157 × 1 / 4x = 39.25x = 39 ( rounded to the nearest whole number as an approximate value )
