Answer:
32c + 27r + 140p + 120e
Step-by-step explanation:
(20c + 15r + 75p + 50e) + (12c + 22r + 65p + 70e)
add like terms that are in the parentheses first together, but the thing is that there isn't any like terms that can be added together within the parentheses so:
20c + 15r + 75p + 50 e + 12c + 22r + 65p + 70e
rearrange to make it easier to look and add, not required
20c + 12c + 15r + 22r + 75p + 65p + 50e + 70e
add like terms
32c + 27r + 140p + 120e
