о o
C. $45
D. $53

Given the function, f(x) = 10x + 8, representing how much Jack earns working for x hours, if Jack works from 2:30 P.M to 7:00 PM, it means Jack worked for 4 hours 30 minutes, which is 4.5 hours (30 minutes = 0.5 hr).

Therefore, to find out how much he earned working for 4.5 hours, substitute x = 4.5 in [tex] f(x) = 10x + 8 [/tex]

[tex] f(4.5) = 10(4.5) + 8 [/tex]

[tex] f(4.5) = 45 + 8 [/tex]

[tex] f(4.5) = 53 [/tex]
