Mr. Ferrier invested $26,000. Some was invested in bonds that made a 5% profit, and the rest was put in stocks that made an 8% profit. How much did mr. Ferrier invest in bonds if his total profit on both types of investments was $1,420

bonds=22000

stock=4000

Step-by-step explanation:

let b for bonds, and s for stock

b+s=26000

0.05 b + 0.08 s=1420

to solve (by elimination)

1 - multiply first equation with 0.05 to eliminate b

0.05 b+0.05 s=1300

0.05b+0.08s=1420

subtract two equations:

0.05b+0.05s-0.05b-0.08s=1300-1420

-0.03s=-120

s=120/0.03=4000

b+s=26000

b=26000-4000=22000

check:0.05 (22000) + 0.08 (4000) = 1420
