Answer:
Odd is the answer.
Step-by-step explanation:
An even number can be written in the form 2x, where x is an integer.
An odd number can be written in the form 2x + 1, where x is an integer.
So two odd numbers can be represented by 2a +1 and 2b +1, the product would be:
(2a + 1)(2b +1) = 4ab + 2a + 2b + 1 = which can be written as 2(2ab + a +b) + 1, but 2ab +a + b represents some integer, so 2ab + a + b = x.
So (2a + 1)(2b + 1) = 2(2ab + a + b ) + 1 = 2x +1 which is odd.

Answer:
She would save £5
Step-by-step explanation:
→ First work out the cost of items for one student. Work out cost of the photocopying
40 × £0.02 = £0.80
→ Add the cost of the one folder
£0.80 + £0.70 = £1.50
⇒ Now we know £1.50 is the amount of money it costs for one student, we multiply that by 120 because there are 120 pupils
£1.50 × 120 = £180
→ £180 is the total cost and now we minus that from the online price of £175
£180 - £175 = £5
