Answer:
25
Explanation:
The way I did this was I added all the numbers together (number through Monday-Friday) and got 17. Then I started off with 20, and multiplied 20 by 0.68 to get 13.6, now I’m trying to get up to 17 so I kept going up by 1 to finally try 25 x 0.68 = 17. Hopefully this makes sense!
