You may be confusing Celsius and Fahrenheit. While $\displaystyle{{25}}^{\circ}\text{F}\usepackage{cmbright}\Huge\$ would be below the freezing point of water (which is $\displaystyle{{32}}^{\circ}\text{F}\usepackage{cmbright}\Huge\$ ), $\displaystyle{{25}}^{\circ}\text{C}\usepackage{cmbright}\Huge\$ is above the freezing point of water (which is $\displaystyle{{0}}^{\circ}\text{C}\usepackage{cmbright}\Huge\$ ). The correct answer is $\displaystyle{{30}}^{\circ}\text{F}\usepackage{cmbright}\Huge\$ .
