Mr eliot is extremely careful with his money. He recently invested part of his $150,000 life savings in gold bullion and the rest in a bank he claims to have a nuclear blast proof safe. Mr elliot earned a 5% profit on his gold bullion investment and a 3% profit on the money in the bank. If he made a total profit of $5,500 from both investments, how much did he invest in gold bullion?

Answer:The amount invested in gold bullion by Mr. Eliot  =   $50,000Step-by-step explanation:Total amount of savings Me. Eliot ha s = $150,000Let us assume the amount invested in gold bullion = $mSo, the amount invested in bank = $150,000 - mNow, 5% on m = [tex]\frac{5}{100}  \times m = 0.05 m[/tex]So, the profit in gold bullion  =  0.05 mand 3% on (150,000 -m)   = [tex]\frac{3}{100}  \times  (150,000 -m) = 0.03  (150,000 -m)  [/tex]= 4,500 - 0.03 mSo, the profit in bank =  4,500 - 0.03 mNow,  the total profit  = $5,500⇒Profit from gold bullion + ban = $5,500⇒0.05 m +  4,500 - 0.03 m = $5,500or, 0.02 m = 1000⇒ m = 1000/0.02 = 50,000Hence, the amount invested in gold bullion  =  m = $50,000
