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?

12h+0.50b+0.25d= total

Step-by-step explanation:

if twelve is the hourly rate, then you would multiply that by the number of hours worked.

0.50 is the amount he is getting paid for bakery items so that sould be multiplied by the amount of bakery items baught.

the same would go for the drinks.
