Rio has £5. He wants to buy a

ruler and some pencils. A ruler
costs £1.45 and each pencil
costs 53p. What is the
maximum number of pencils
Rio can buy?

Answer 1

6

Explanation:

call £5 500p.

£1.45 =145p

500 - 145 = 355.

355/53 = 6.7

so the maximum number of pencils he can buy is 6.

you can check this by inputting those numbers.

£1.45 + 6 X £0.53

= £1.45 + £(3.18)

=£4.63

Rio still has 37p left. not enough for another pencil

Answer 2

6

Explanation:

£5 - £1.45 = £3.55

£3.55 ÷ 0.53p = 6.698

since you cant have .6 of a pencil, the maximum number of pencils Rio can buy is 6
