The coldest temperature in the city today was $\displaystyle{14.8}\usepackage{cmbright}\Huge\$ degrees (Fahrenheit) lower than the hottest temperature. Let $\displaystyle{H}\usepackage{cmbright}\Huge\$ represent the high temperature and let $\displaystyle{L}\usepackage{cmbright}\Huge\$ represent the low temperature.

i) What is a formula that correctly relates $\displaystyle{H}\usepackage{cmbright}\Huge\$ and $\displaystyle{L}\usepackage{cmbright}\Huge\$ ?

ii) If the low temperature was $\displaystyle{68.9}\usepackage{cmbright}\Huge\$ degrees, what was the high temperature?
