SpongeBob loves to grow flowers for his pal Sandy, who loves big, colorful flowers. He found a new brand of seeds coated with a special “booster” fertilizer that said it would produce huge flowers. He planted 5 of the new seeds in one container and 5 of the old brand of seeds in another container. He placed both containers on a sunny windowsill and watered them every day. He measured the diameter of each flower, which is shown in the chart.
