Answer 1

9514 1404 393

Answer:

• 6 apples
• 3 pears

Explanation:

Let p represent the number of pears sold. Then 9-p is the number of apples sold. The total revenue was ...

0.25(9 -p) + 1.15p = 4.95

0.90p +2.25 = 4.95 . . . . . . collect terms

0.90p = 2.70 . . . . . . . . . . subtract 2.25

p = 3 . . . . . . . . . . . . . . . divide by 0.90

They sold 3 pears and 6 apples on Thursday.
