in March, let their individual savings be
a, b, c, and d > a+b+c+d = 1440
in April,
Oliver: 2a
Asia: b30
Hassan: c
Abby: d+46
total = 2a + b30 + c + d+46
= a + b + c + d + a + 16
= 1440 + a + 16 = 1456 + a
also: 2a = b30 = c = d+46
b 30= 2a , > b = 2a+30
c = 2a
d+46 = 2a > d = 2a46
so in a+b+c+d=1440
a + 2a+30 + 2a + 2a46 = 1440
7a = 1456
a = 208
total in April = 1456+a = 1456+208 = 1664
check:
a=208, b=446 , c = 416, d = 370
March: 208+446+416+370 = 1440
April: 416+416+416+416 = 1664
