Answer:

0.02x + 0.04(800) = 112

Step-by-step explanation:

Let the unknown amount be x

The amount is invested at 2 % interest so the intrest will be $ 0.02x

However, another amount, this time $ 800 is invested at 4 % interest. This gives:

0.04 (800)

The total amount at the end of the year will be = $ 112

Therefore, the sum of the two interests will be $\\$ 0.02x+ 0.04($800) = $ 112.00$
