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. ( what is an expression/equation for each persons amount of money saved?)
