At Rosie's Roses, the price of a long-stemmed rose depends on its color, but Rosie does not post the price per rose. A bouquet of 4 red, 3 white, and 2 pink cost $39; a bouquet of 6 red, 2 white, and 4 pink costs $52.50; and a bouquet of 5 red, 1 white, and 5 pink costs $46. How much will you pay for 4 roses of each color?
