10:14, 15:21, 20:28 would be a few. Add five two the first and seven to the second number.
Answer:
yeah i am really bored
Step-by-step explanation:
The text tells us 215 is 86% of the questions
We are looking for 100% of the questions
We get that number by:
Multiplying 100 and 215 and dividing it by 86

And that equals 250
Well, you need write the system of equation:
If we call "P" to quantity of pencils and we call "N" to quantity of notebooks, the total quantity of articles in an equation is:
P+N=19
And the total money that Joanna spent in an equation is:
$1.46*P+$2.41*N=$32.49
Now you only need to solve that system.
Good luck!
