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?

area of part 1:

a1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2

area of part 2:

a2=length*width=(8+2)*1=10 ft2

area of part 3:

a3=length*width=8*2=16 ft2

total shaded area : a1+a2+a3=41 ft2

total area of the reactangle : a=16*8=128 ft2

total area of the nonshaded region : 128-41=87 ft2
