Marvin inherited $25,000 from his grandparents. He placed the money in three different accounts that earn 2%, 6.25%, and 8.5% annual simple interest. The amount of money placed in the account that earns 2% was half the amount of money placed in the account that earns 6.25% interest. If he earned $1729 in interest combined after one year, how much money did he place in each account? I NEED THIS IN 20 MINUTES

let soccer = x and golf = y

part a

1st equation: x + y = 125

2nd equation: x = y +45

part b

replace x in the 1st equation with the 2nd one:

y + 45 + y = 125

simplify:

2y + 45 = 125

subtract 45 from each side:

2y = 80

divide both sides by 2:

y = 80/2

y = 40

she plays golf for 40 minutes.

part c

no because she plays soccer for 45 minutes longer than golf 40 +45 =   85 minutes, not 80 minutes.
