3 Verona is an artist in Marfa, Texas, who paints the Marfa lights over a field. She prints postcards of her paintings to sell to tourists. The cost to print postcards is a
flat $60 fee plus $0.25 per postcard. She sells the postcards for $1.25 each. Write an
equation that represents Verona's costs and an equation that represents her
earnings on sales. How many postcards must she sell before she starts making
a profit?

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 )
