Answers:
She made ___25___ grams of ___40___% salt solution
------------------------------------------------------------------
The given info "20 grams of 50% salt solution" tells us that we have 10 grams of pure salt
Since 50% of 20 = 0.50*20 = 10
Put another way, we have 10 grams of pure salt out of 20 total so 10/20 = 0.50 = 50% salt solution
The 20 grams of solution updates to 25 grams of solution when we add the 5 grams of water
We don't add any salt, assuming this water is fresh water
So we still have 10 grams of pure salt out of 25 grams now
10/25 = 2/5 = 0.40 = 40% is the new salt concentration

3. 2 cups of yellow 40 cups of blue 4. 2 cups of yellow 30 cups of blue
Step-by-step explanation:
1. to get same shade keep ratios the same but divide by 2 for smaller amount
2/2 = 1 and 35 /2 = 17.5
2. similar to 1. except multiply by 2
3. use same yellow amount but more blue
