Answer 1

20% + 40% = 60%
100% - 60% = 40%

40% of 420
= (420/100) × 40
=168

Joanna makes 168 egg sandwiches

Answer 2

20% as a decimal is 0.20. So, 240 x 0.20 is 48 tuna sandwiches, 40% as a decimal is 0.40 so 240 x 0.40 is 96 ham sandwiches. 48 + 96 is 144. So that means that the remaining 96 sandwiches are Egg Salad Sandwiches.
