Answer:
the length of flower at the end of week is 10 7/8 inches.
Explanation:
Original height = 9 3/4 inches
=> 39/4 inches
Growth in one week = 1 1/8 inches
=> 9/8 inches
The height by the end of week = Original height + growth
=> 39/4 + 9/8
=> (39*2)/4*2 + 9/8
=> 78/8 + 9/8
=> 87/8 inches
=> 10 7/8 inches
Therefore, the length of flower at the end of week is 10 7/8 inches.
