Adiscount book store sells hardcover books for $8 each and paperbacks for $4 each. the number of hardcover books,  h,  sold one day was 2 more than four times the number of paperback books,  p, sold that same day. the total amount of sales for that day was $160. jean-paul wrote the following system of linear equations to find the number of each type of book sold.8h+4p=160 p=4h+2what is jean-paul’s error? a. jean-paul should have written the first equation as  h+p=160b. jean-paul should have written the first equation as  4h+8p=160c. jean-paul should have written the second equation as h=4p+2d. jean-paul should have written the second equation as p+2=4h

C. Jean-Paul should have written the second equation as h=4p+2

Step-by-step explanation:

Let the hardcover books be denoted by = h

Let the paperback books be denoted by = p

A discount book store sells hardcover books for $8 (8h) each and paperbacks for $4 each (4p).

The total amount of sales for that day was $160. Equation forms:

The number of hardcover books, h, sold one day was 2 more than four times the number of paperback books, p, sold that same day. Equation forms:

Now we can see that Jean Paul made a mistake writhing this second equation. She interchanged 'p' and 'h'.

So, the correct answer is option C.

answer: c.  

step-by-step explanation:

mixtures containing substances that get attracted to magnet can be separated using a magnet. we can separate iron from a mixture of sand and iron, as only iron attracts to the magnet.

c) the median for town a 30" is greater than the median for town b 25"

step-by-step explanation:

town a, median = q2 = 30

town b, median - q2 = 25

so the median for town a 30" is greater than the median for town b 25"
