Answer:
8x +5y
Step-by-step explanation:
As with any purchase, the extended amount of the bill for an item is the product of the number of items bought and the price of each of them. The total bill is the sum of the extended amounts.
On Samuel's first visit he paid ...
3x +2y . . . . . dollars for apples and spinach
On Samuel's second visit, he paid ...
5x + 3y . . . . . dollars for apples and spinach
Then the total he spent was ...
(3x +2y) +(5x +3y) = (3x +5x) +(2y +3y) = 8x +5y
