5) A. Marked price - Sale price

Explanation:
1) The square of 4 is just 4x4, which equals 16.

2) We have to first work out the square of 3457.
3457 x 3457= 11,950,849
The last digit is 9.

3) We know that 8 squared is 64, so the square root of 64 is 8.

4) To simplify 2:4, we need to divide both sides by a common factor. The common factor in this case is 2.
2 ÷2= 1
4 ÷2= 2
2:4 = 1:2

5) A discount is the more expensive/ marked price - the cheaper/ sale price.

Hope this helped you!
