The question you asked is about how to find the number of jelly beans that Jessica has left after she gives some to her friends and her sister. You provided the following information:
Jessica has 10j jelly beans, where j is a positive integer.
She gives j jelly beans to each of her four friends and 5 jelly beans to her sister.
To answer this question, you need to use the formula for subtraction, which is:
Difference = Minuend - Subtrahend
where the difference is the result, the minuend is the number being subtracted from, and the subtrahend is the number being subtracted.
In this case, the minuend is the number of jelly beans that Jessica has at the beginning, which is 10j. The subtrahend is the total number of jelly beans that Jessica gives away, which is j * 4 + 5. Therefore, you can plug in these values into the formula and get:
Difference = 10j - (j * 4 + 5) Difference = 10j - 4j - 5 Difference = 6j - 5
This means that the number of jelly beans that Jessica has left after she gives some to her friends and her sister is 6j - 5. Therefore, the answer to your question is:
In terms of j, Jessica has [6j - 5] jelly beans left.
