Answer 1

Answer: option 2 is the cheapest

Step-by-step explanation:

Option 1 :

10% of 4.99 = 0.499

10% off 4.99 =

4.99 - 0.499 = 4.491

10% of 15.99 = 1.599

10% off 15.99 =

15.99 - 1.599 = 14.391

10% of 30.99 = 3.099

10% off 30.99=

30.99 - 3.099 = 27.891

Total = 4.491 + 14.391 + 27.891 = 46.773

Option 2 :

Most expensive item = 30.99

20% of 30.99 = 6.198

20% off 30.99=

30.99 - 6.198 = 24.792

Total = 24.792 + 15.99 + 4.99 = 45.772

Therefore, option 2 is cheaper by 1.001.

Hope this helped :)
