Answer:
The plumbers cost would be equal to the equation 80+45x=y with y being the total amount of money he made and x being how many hours he worked.
Step-by-step explanation:
In this equation to find the amount the plumber was paid all you need to do is plug in the amount of hours he worked for x.

Answer:
280.8 pounds
Step-by-step explanation:
Original weight of pig = 54 pounds
Percentage increase in weight = 420%
Current weight of pig = original weight + 420% of original weight

= 54 + 4.2 * 54
= 54 + 226.8
= 280.8 pounds
Current weight of pig = 280.8 pounds
