Answer :
31x3=93
12x8=96
96-93=3
So their will be 3 cookies left for our beautiful teacher Mrs.Tofa
Equation 2
On a cool day the school swimming pool will have around 1700 litres of water. However on a hot day, the water level drops by 178 litres. How many litres of water will be in the pool on a hot day?
Answer:

1000 - 170=830
700 - 8=692
830 + 692=1522 litres on a hot day
