Maggie bought a total of 30 pounds of three different types of produce to feed her hungry hippopotamus. bananas cost $1 per pound; guavas cost $2 per pound; and dragon fruit costs $3 per pound. maggie spent $46. the weight of the bananas that maggie bought was twice the weight of the guavas and dragon fruit combined. write a written systems of equations consisting of three variables that can be used to determine how many pounds of each fruit maggie bought? (there are three correct answers) b = 2 ( g + d ) b + 2g + 3d = 46 30b + 30g + 30d = 1 b + 2g + 3d = 30 b + g + d = 30 b + g + d = 46 2b = g + d
