D.
12

Answer 1

Answer:

D. 12 bags

Step-by-step explanation:

if each bag = 40/3 pounds

and the total = 160 pounds

Answer = 40/3 of X = 160 pounds

= 40/3  ×  X = 160 pounds

X(40/3) = 160 pounds

divide both sides by 40/3

X = 160 ÷ 40/3

invert the fraction to change the division sign to a multiplication sign

X = 160 × 3/40

X = 480/40

X = 12 bags
