Answer:
[tex]27^{\circ}F[/tex]
Step-by-step explanation:
Use formula
[tex]F=1.8C+32[/tex]
to convert Celsius to Fahrenheit.
When [tex]C_1=0^{\circ}C,[/tex] then
[tex]F_1=1.8\cdot 0+32\\ \\F_1=32^{\circ}F[/tex]
When [tex]C_2=15^{\circ}C,[/tex] then
[tex]F_2=1.8\cdot 15+32\\ \\F_2=27+32=59^{\circ}F[/tex]
Difference:
[tex]F_2-F_1=59^{\circ}F-32^{\circ}F=27^{\circ}F[/tex]
