Suppose 8x + 16 ice cream cones were sold on Saturday and 7x - 9 were sold on Sunday. What is the total number of ice cream cones sold?
• 15x + 25
15x + 7
x + 7
x + 25
The total number of ice cream cones sold can be found by adding the number of cones sold on Saturday and Sunday:
8x + 16 + 7x - 9
Combining like terms:
(8x + 7x) + (16 - 9)
15x + 7
So, the total number of ice cream cones sold is 15x + 7.
