There were chews for 2p, mini eggs for 3p, Chocko bars for 5p and lollypops for 7p in the sweet shop. What could each of the children buy with their money?

# Plenty of Pens

##### Stage: 2 Challenge Level:

Adrian has worked out this problem very efficiently:

No of pencils $= x$
No of pens $= 4x$

Spent on pencils $= 10x$
Spent on pens $= 4x \times15 = 60x$
Total spent $= 10x + 60x = 70x$

$70x = 250 - 40$
$70x = 210$
$x = 210 / 70 = 3$

Therefore no of pencils $= 3$
No of pens $= 3 \times4 = 12$

Pupils at Moorfield Juniors, including Emma, approached it slightly differently:

We worked this out by taking 40p from £2.50 which is 2.10 then using trial and error.
It was easy because there aren't many low numbers in the 4 times table.
The answer is 12 pens which equals £1.80. 12 divided by 4 = 3 so there are 3 pencils which equals 30p.
£1.80+30p=£2.10.
