1) Listen 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" · 1.05", 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 1.05 + 2y, but he made a mistake. How can the collector correct his mistake? Select from the drop-down lists to correctly complete the sentence. The base of the simplified expression should be and the exponent should be Calculator
