Pls elaborate on how 8.4u+39.20=140 come abt. Thanks
Amount of money receive are fixed each month.
Since the spending for Rachel is reduced 1/2 from 1st month to 2nd month., and Elijah spent increased by half, therefore Elijah will spent all the money faster (2x), mean 1st month take 24 days, 2 nd month will be 12 days spent all her money.
8.4u is came from 3 x 2.8u
39.20 is different balance from 1st month.
All this added together is same as 140 from 2nd month since they received fix amount every month.

Check on this model. Take note on Rachel money spend in Red shaded parts for 1st and 2nd month.
