The cost of 2 erasers and 7 rulers is $3.95
Find cost of 2 erasers and 2 rulers.

Should the qn be 3erasersn 7 rulers=3.95

Then u simply add to get 10erasers n 10rulers=9.00
So 1 eraser n 1 ruler=0.90

If based on qn post the kid must know how to multiply decimal number n division of double digit number, at this point of time, the skill requirement is too much for p3 kid to handle.... Cheers

Oh really? Is 3 erasers and 7 rulers…


The answer given was $2, so there’s typo error in the test paper?
