Question

To the nearest pound, Tim has £8

To the nearest 50p, Sue has £4.50
Work out the maximum possible total amount of money.
Give your answer in pounds (£).

Answer 1

Explanation:

to the nearest pound, tim has £8

=> 7.5 ≤ Tim has < 8.5

sue has £4.50

to the nearest 50 p

=> 4.25 ≤ Sue < 4.75

=> possible total amount of money

= 7. 5 + 4.25 ≤ Amount < 8.5 + 4.75

=> 11.75 ≤ Amount < 13.25

maximum possible total amount of money would be less than 13.25

and in term of paisa maximum < 4.75 = 4.74

and maximum less than < 8.5 = 8.49

Hence maximum possible total amount of money would be = 13.23 £
