Question

Caroline buys 5 rubbers and 5 crayons for £10.

Elliot buys 1 rubber and 2 crayons for £2.75.

Work out the cost of one rubber and one crayon.

Answer 1

5R + 5C = 1000

1R + 2C = 275

(1R + 2C = 275) x 5 = 5R + 10C = 1375

(5R + 10C = 1375) - (5R + 5C = 1000) = 5C =375

CRAYON = 75p

RUBBER = 125p
