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?

Accepted Solution

A:

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
