Answer:
Each of them eat 140 scoops.
Step-by-step explanation:
Let x be the amount eaten by each of them,
Given,
The initial ice cream Masha has = 200 scoops
Final ice cream Masha has = ( 200 - x ) scoops
while the initial ice cream Liz has = 180 scoops,
Final ice cream Liz has = (180-x) scoops,
According to the question,
![\frac{200-x}{180-x}=\frac{3}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B200-x%7D%7B180-x%7D%3D%5Cfrac%7B3%7D%7B2%7D)
( by cross multiplication )
( Subtracting 400 on both sides )
( adding 3x on both sides )
Hence, each of them eat 140 scoops.
