A collector purchased a rare coin for $100. After the purchase, the coin’s value increased by 10.25% per year for the first x years and 5% per year for the next y years. The expression 1.1025 x ⋅ 1.05y when multiplied by 100, reveals the value of the coin, in dollars, (x+y) years after the coin was purchased. The collector simplified the expression to 1.05x+2y, but he made a mistake. How can the collector correct his mistake?
The base of the simplified expression should be (1.05, 1.1025), and the exponent should be (2xy, x+y, x+2y, 2x+y, 2x+2y).
