Her teacher would be 42. you would take 14 * 3 and get the teachers age.
Lets say x is quantity
65%x+25%(600-x)=45%of 600
.65x+.25(600-x)=.45*600
.65x+150-0.25x=270
0.4x=120
x=300ml

#8: 15
#9: You'd round 0.9 to 1 and 3.78 to 4. 4/1 = 4
#10: Round 2.5 to 3. 36/3 = 12
#11: If they want you to round 0.25 down to 0, then 7/0 is undefined.
#12: 9.5 rounds to 10 142.5 rounds to 143. 143/10 = 14.3
#14: 24.8 cm divided by 175 = approximately 0.1417 cm per year. Round that up to approximately 0.14 per year.
