Answer:
16 4/5 inches
Step-by-step explanation:
We can find the amount it will grow by taking the rate it grows times the time
growth = rate* time
= 2 2/5 * 7
Changing the mixed number to an improper fraction
2 2/5 = (5*2+2)/5 = 12/5
growth = (12/5)*7
=84/5 inches
Changing this back to a mixed number
5 goes into 84 16 times (5*16 = 80 ) with 4 left over
16 4/5 inches
