Answer: $36 per rosebush without the discount
==========================================================
Step-by-step explanation:
x = full price for one rosebush
x-12 = discount price (saving $12) for each rosebush
4(x-12) = total for buying four rosebushes at the discount price
4(x-12) = 96 since she paid $96 overall through the discount
------------------------
Let's solve for x
4(x-12) = 96
x-12 = 96/4
x - 12 = 24
x = 24+12
x = 36
Or you could solve like this
4(x-12) = 96
4x-48 = 96
4x = 96+48
4x = 144
x = 144/4
x = 36
Either way, the full original price per rosebush was $36
Saving $12 per rosebush means she actually paid 36-12 = 24 dollars per plant instead. Then note how 24*4 = 96 to help fully confirm we have the correct x value, and it confirms the correct answer.
