Jackson invested $300,000, dividing it all unequally between Account P and Account Q. At the end of the year, it turned out that Account P had earned 12% interest and Account Q had earned 25% interest. If Jackson earned a total of$60,000 in interest between the two accounts, which of the following is approximately the amount he put in Account P?

A. $115,384 B.$120,000
C. $121,072 D.$124,129
E. $130,000 OA A We can solve the question using 1 variable or 2 variables. Let's use 1. Let x = the money (in dollars) placed in Account P So,$300,000 - x = the money placed in Account Q

Account P earned 12% interest and Account Q earned 25% interest, and Jackson earned a total of \$60,000 in interest between the two accounts
We can write: (12% of x) + (25% of 300,000 - x) = 60,000
In other words: 0.12x + 0.25(300,000 - x) = 60,000
Expand: 0.12x + 75,000 - 0.25x = 60,000
Simplify: -0.13x + 75,000 = 60,000
Subtract 75,000 from both sides: -0.13x = -15000
Solve: x = 15,000/0.13 ≈ 115,000
