Total number of cards = 32(4) or y=32(4)
Roberto had 128 cards.
Step-by-step explanation:
Consider the provided information.
Part (A)
He gave his four friends 32 baseball cards each.
Let the number of cards he have before giving them to his friends is y.
This can be written as:
y = 32(4)

y = 32(4)
Multiply 32 with 4
y = 128
Hence, Roberto had 128 cards.
