Batteries are sold in boxes and packets

Each packet contains 8 batteries
Each box contains 25 batteries

Jonathon buys p packets of batteries and b boxes of batteries
write down an expression of the terms p and b for the total number of batteries bought

8p + 25b

Step-by-step explanation:

The expression of the word problem above can be written thus:

answer: the answer is one of

step-by-step explanation:   we are given to write a proper fraction where the whole is divided into an even number of equal parts less than ten, and an odd number of those parts exist.

an even number less than 10 may be one of 2, 4, 6 or 8. so, the whole may be one of these four evens.

now, an odd number of these parts must exist, so the numerator must be an odd number, one of 1, 3, 5 or 7. it cannot be 9 because then the fraction will become improper.

thus, our fraction may be one of the following

use this formula:

p(a\b) = p(a and b)/p(b).

take it from here.
