Answer:

Your answer should be $29.40

Step-by-step explanation:

If you divide 21 by 5 you get 4.2, so each book costs $4.20.

4.2 x 7 = 29.4

Therefore, your total cost for 7 books will be $29.40

I hope this helps!

What number am I
laiz [17]

Answer:

21

Step-by-step explanation:

So, factors of 6 that are between 17 and 25 are 18 and 20, so that's not the numbers.

Multiples of 3 are 18, 21, and 24.

The only number that would be reasonable enough is 21, because it is a multiple of 3 and is not a factor of 6.
