Line a is parallel to line b, m 6=85 and m 3=2x. Find m 1.

Isabella has twice as much money invested at 4% as she has invested at 3%, and she has $500 more invested at 5% than she has at
adell [148]
Invested at 3% = x
invested at 4% = 2x
invested at 5% = x+500

0.03x + 0.04(2x) + 0.05(x+500) = 2025
0.03x + 0.08x +0.05x +25 = 2025
0.16x = 2000
x= 12,500
4% = 2x = 12,500 * 2 = $25,000
