Answer:
They each donated 56 books
Step-by-step explanation:
O = 176
D = 80
O - a = 5(D - a)
176 - a = 5(80 - a)
176 - a = 400 - 5a
4a = 224
a = 56
Answer:
Each person donated 56 books.
Step-by-step explanation:
Let d represent the # of books donated by each person. Then:
in Olivia's case, 176-d = 5(80-d). Then 176-d = 400 - 5d.
Solving for d: 4d = 224, and d = 56.
Each person donated 56 books.
