Apologies for the confusion. Let me double-check my calculations.
Using the system of equations:
x + y = 19
11x + 15y = 225
By multiplying the first equation by -11, we get:
-11x - 11y = -209
Adding this to the second equation:
(11x + 15y) + (-11x - 11y) = 225 + (-209)
4y = 16
Dividing both sides by 4:
y = 4
Substituting this value back into the first equation:
x + 4 = 19
x = 19 - 4
x = 15
So, the correct statement is:
Jim bought 15 petunias.
