Word Problem I need help to set up the equation.
Osborne invested $17000 in stocks and bonds. if he made a 10% profit on his stocks and a 7% profit on his bonds, and the combined profit was $1,280, how much did Osborne invest in stocks?
 
Let x = the amount of money Osborne invested in stocks
Let y = the amount he invested in bonds
 
We have two unknowns (x and y) so we need two equations relating the unknowns to solve the problem.
 
Equation 1: Osborne invested $17000 in stocks and bonds
 
x + y = 17000
 
Equation 2: He made a 10% profit on his stocks and a 7% profit on his bonds, and the combined profit was $1,280
 
x*(0.10) + y*(0.07) = 1280
 
OK, I set it up for you.  Can you finish it from here?
another solution:
 
S=amount invested in stocks
$17,000-S=amount invested in bonds
10%*S+7%*($17,000-S)=$1280
10%*S+7%*($17,000)-7%*S=$1280
0.1S+$1190-0.07S=$1280
0.03S=$1280-$1190
0.03S=$90
3S=$9000
S=$9000/3
S=$3000 invested in stocks
$17,000-$3000=$14,000 invested in bonds
check:
10%*$3000+7%*$14,000=(0.1*$3000)+(0.07*$14,000)=$300+$980=$1280
