A- Php 46.00 is he's change

Answer:

46

Step-by-step explanation:

1 dozen is equal to 12. Since the price is 4.50 per egg, you have to multiply 12 and 4.50 which is equal to 54. Since Joseph has a 100-peso bill, you subtract 54 from 100.  

12 x 4.50 = 54

100 - 54 = 46

So the final answer is 46
