Answer:tammy's rosebush has 30 blooms.
Explanation:
Let x represent the number of blooms that tammy's rosebush have.
Mika's rosebush had 24 blooms in the first week of may. This was 80% as many blooms as tammy's rosebush had during the same period. This means that
24 = 80% of x
24 = 80/100 × x = 0.8 × x = 0.8x
Dividing the left hand side and the right hand side of the equation by 0.8x, it becomes
24/0.8 = 0.8x/0.8
x = 30
