An airline increases the prices of its flights by \( 8 \% \). (a) Before the increase, the price of a flight to Cairo was \( £ 475 \) Work out the price of a flight to Cairo after the increase.

16 Assume that the current population of a large region is 340 million. It was reported that the population grew \( 10.4 \% \) since it was last measured 10 years previously, Use the model \( \mathrm{A}=\mathrm{A}_{0} e^{\text {kt. }} \). Complete parts a through c below. a. What was the population when it was measured 10 years ago? The population was \( \square \) million the first time it was measured. (Round to one decimal place as needed.)

1. Em uma das situações estudadas aprendemos que as escalas Celsius Fahrenheit, utilizadas para expressa medidas de temperatura, não sãc proporcionais. A relação matemática entre elas é dada pela expressão: \( \begin{array}{l}\mathrm{F}=1,8 \cdot \mathrm{C}+32 \text {, em que } \mathrm{F} \text { é dado } \\ \mathrm{em}{ }^{\circ} \mathrm{Fe} \mathrm{C} \text { é dado em }{ }^{\circ} \mathrm{C} .\end{array} \) \( \begin{array}{ll}\text { Com isso, determine: } \\ 68^{\circ} \mathrm{F} \text { em }{ }^{\circ} \mathrm{C} & \text { b) } 25^{\circ} \mathrm{C} \mathrm{em}^{\circ} \mathrm{F} .\end{array} \)
