d represents the number of daises purchased.
She purchased 12 bumdles of tulips
If both types of flowers cost $4 per bundle, then the cost of both flowers is
4(d + 12)
If she spent $76 on flowers, then the correct equation would be
4(d + 12) = 76
Dividing both sides by 4, we have
d + 12 = 19
d = 19 - 12
d = 7
Option A is correct
