The function which can be used to calculate his earnings is the sum of three components.

1. Student earns an hourly rate of $12. If he workes h hours, then he earns $12h per h hours.

2. Student an extra $0.50 for each bakery item he sells. If he sells b bakery items, then he earns $0.50b in total.

3. Student an extra $0.25 for each drink he sells. If he sells d drinks, then he earns $0.25d in total.

Therefore, the function is

[tex]f(x)=12h+0.50b+0.25d.[/tex]

Answer:

T = 12h + b/2 + d/4
