Bill invests a total of $6000 for one year in two savings accounts, a money market account, and a passbook account. In his money market account, he earns 5% simple interest. In his passbook account, he earns 4% simple interest. At the end of one year, Bill earned a total of $270 interest in his two savings accounts. Which equation is used to calculate x, the amount Bill invested in his money market account? (x)(0.05)(1) + (6000 − x)(0.04)(1) = 270
(6000 − x)(0.05)(1) + (x)(0.04)(1) = 270
(6000 − x)(5)(1) + (x)(4)(1) = 270
(x)(0.05)(1) + (x)(0.04)(1) = 6000
(x)(5)(1) + (6000 − x)(4)(1) = 270
