Pink: 2lbs = $6.40
Blue: 4-oz = $1.00
Green 1lb 8oz = $4.20

Pink = $3.20 per pound
Blue = (4 oz = 1/4 a pound) $4.00 per pound
Green = (8 oz = 1/2 a pound)(1lb 8 oz = 150% = 1 price + 1/2 of that price to equal $4.20) $2.80 per pound ($2.80 plus 1/2 of $2.80 ($1.40) = $4.20)


Karen should buy the GREEN sprinkles because it costs the least ($2.80) per pound, whereas blue costs $4.00 per pound, and pink costs $3.20 per pound.
