The company sold 6400 dolls when 28,000 was spent on advertising and the price of a doll was set at $40. Determine the number of dolls sold when the amount spent on advertising is increased to $56,000. Round to the nearest whole number

the correct option is 2.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)
