Answer 1

Answer:

C. 34%

Step-by-step explanation:

I already answered this, but here goes.

Hello there!

Divide the solutions into 100s, and find their percentages.

60/100=0.6*40=24

40/100=0.4*25=24+10

24+10=34 %

;)

Answer 2

Answer:

34%

Step-by-step explanation:

To find the concentration of the new solution, take the percent time the amount of each of the solutions

40 ml* 25% + 60 ml * 40% = 100 ml* percent

40 * .25 + 60 *.40 = 100 * P

10 + 24 = 100 P

34 = 100 P

Divide each side by 100

34/100 = P

.34 = P

Changing to a percent

34% = P
