in march, the savings of oliver, asia, hassan, and abby was \$1440. in april, their savings became equaly when oliver's savings is doubled, asia's savings is decreased by \$30, abby's savings is increased by \$46, and hassan remained the same. find the total saving in april.

• math -

in March, let their individual savings be
a, b, c, and d ---> a+b+c+d = 1440

in April,
Oliver: 2a
Asia: b-30
Hassan: c
Abby: d+46
total = 2a + b-30 + c + d+46
= a + b + c + d + a + 16
= 1440 + a + 16 = 1456 + a

also: 2a = b-30 = c = d+46

b -30= 2a , ---> b = 2a+30
c = 2a
d+46 = 2a ----> d = 2a-46

so in a+b+c+d=1440
a + 2a+30 + 2a + 2a-46 = 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
