Stacy, Oliver, and Jivesh each plan to put a certain amount of money into their savings accounts that earn simple interest of 6% per year. Stacy puts $550 more than Jivesh, and Oliver puts in 2 times as much as Jivesh. After a year, the amount in Stacy's account is 2 times the sum of $212 and the amount in Oliver's account.

Respuesta :

J = 106% . x
S = 106% . (550+x)
O = 106% . 2x

S = 2(212+O) = 106%(550+x)
S = 424 + 2O = 583 + 106%x
2(106%.2x) - 106%x = 583-424
159 = 106%x( 4 - 1 )
159 = 106%x ( 3 )
159 = 318%x
1 = 318%x : 159
1 = 2%x
1 = 2/100 . x
x = 50

Jivesh put $50
Stacy put $600
Oliver put $100
