Question

A notebook costs £1.60, a pen costs 37p, a pencil costs 21p and a sharpener costs 86p.

Remi buys 3 pencils, 2 pens, 3 sharpeners and some notebooks.
He pays with £8 and receives 85p change.
How many notebooks did he buy?
notebooks

Answer 1

2

Explanation:

£1 = 100p

3*21p+2*37p+3*86p+x*160p (x is the number of notebooks)

63p+74p+258p+x*160p = 395p+x*160p

He paid £8 so he paid 800p

800p-395p = 405p

405p-85p = 320p

320p:160p = 2

He bought 2 notebooks

Answer 2

£1.60 each notebooks
3 pencils times 21p= 63p
2pens times 37p=74p
3sharpeners times 86p=258p
63p+74p+258p=£3.95
£8-3.95=£4.05
£4.05-£1.60= £2.45
£2.45-£1.60=85p
So… he bought 2 notebooks
