x+y=15
8x+5y=96
now just solve for x and y
8x+5y=96
now just solve for x and y
Let's assume Arianna bought x pink flowering plants.
Since pink flowering plants cost $8 each, the cost of x pink flowering plants would be 8x dollars.
We also know that Arianna bought a total of 15 flowering plants for $96.
So, the number of purple flowering plants she bought would be 15 - x.
Since purple flowering plants cost $5 each, the cost of (15 - x) purple flowering plants would be 5(15 - x) dollars.
We can now set up an equation based on the total cost of the plants:
8x + 5(15 - x) = 96
Simplifying this equation, we have:
8x + 75 - 5x = 96
3x + 75 = 96
3x = 96 - 75
3x = 21
x = 21/3
x = 7
Therefore, Arianna bought 7 pink flowering plants.
