Answer:
Step-by-step explanation:
The mass of the solution is 190 g - 120 g = 70 g. Thus, it's density is 70 g / 50 mL = 1.4 g/mL.
change to improper fractions
77 1/2 = 145/2
2 1/4 = 9/4
divide
145/2 divide 9/4
copy dot flip
145/2 * 4/9
580/18
290/9
32 2/9
it will fit into 32 bags with 2/9 left over
We have 32 full bags * 2.25 = $72.00
