At first. the ratio of Sean’s savings to Eugene’s savings was 3:7. After each of them bought a similar laptop for $1488. the ratio of Sean’s savings to Eugene’s savings became 1:4. What was the total sum of savings Sean and Eugene had at first?
S==Sean, E==Eugene
S / E ==3 / 7
[S - 1488] / [E - 1488]==1 / 4, solve for S, E
S ==$2,678.40 - what Sean started with.
E==$6,249.60 - what Eugene started with.
$2,678.40 + $6,249.60 ==$8,928.00 - total sum of both.
