Explicación paso a paso:

$2 1 \div 100 = 0.21 \\ \\ 487 \times 0.21 = 102.27 \\ \\ 487 + 102.27 = 589.27 \\ \\ x = 589.27 \\ \\ \\ \\ 15 \div 100 = 0.15\\ \\ 234 \times 0.15 = 35.1 \\ \\ 234 + 35.1 = 269.1 \\ \\ x = 269.1 \\ \\ \\ 17 \div 100 = 0.17 \\ \\ 340 \times 0.17 = 57.8 \\ \\ 340 + 57.8 = 397.8 \\ \\ x = 397.8 \\ \\ \\ 52÷100= 0.52 \\ \\ 969 \times 0.52 = 503.88 \\ \\ 969+503.88=1,472.88 \\ \\ x= 1,472.88$
