A student gets paid to sell food and drinks at the school play during intermission. He earns an hourly rate of $12, plus an extra $0.50 for each bakery item he sells and $0.25 for each drink he sells. If h=hours, b=bakery items, and d=drinks, what function can he use to calculate his earnings?
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
\(f(x)=12h+0.50b+0.25d.\)
Answer:
T = 12h + b/2 + d/4
