pphalke · Answer

ok

photon336 · Answer

the investments produced a total of $191 interest in 1 yr. how much did he invest at each rate? 

he invests some money at 6%  translates to 0.06x 

$1900 less than the amount at 5%. so less than means subtraction so it becomes

(1900-x) and we take 5% of the total, so we multiply the whole thing by 0.05

0.05(x-1900)


$$0.06x+0.05(x-1900) = 191$$


now we get  0.06+0.05 =

This should be the correct expression can you solve this now? 

 0.11x-1900 =191 

0.11x = 2091

@Photon336 i get a weird number when i divide by 0.11x it comes out 19009.09
