They are left with 0.51 pounds of clay.

Step-by-step explanation:

Given,

Amount of clay bought = 3.8 pounds

Amount used by Martha = [tex]\frac{1}{4}\ of\ clay[/tex]

Amount used by Martha = [tex]\frac{1}{4}*3.8=0.95\ pounds[/tex]

Amount left after Martha's use= Total amount - amount used by Martha

Amount left = 3.8 - 0.95 = 2.85 pounds

Amount used by Scott = [tex]\frac{2}{5}\ of\ amount\ left[/tex]

Amount used by Scott = [tex]\frac{2}{5}*2.85=\frac{5.70}{5}[/tex]

Amount used by Scott = 1.14 pounds

Amount left after Scott's use = Amount left after Martha's - Amount used by Scott

Amount left after Scott's use = 2.85 - 1.14 = 1.71 pounds

Amount used by Alison = 1.2 pounds

Amount left = Amount left after Scott's use - Amount used by Alison

Amount left = 1.71 - 1.2 = 0.51 pounds

They are left with 0.51 pounds of clay.
