Answer:
Step-by-step explanation:
By this age you can give your kitten 1/3 to 1 cup of kitten food per feeding three times a day. If giving wet food, you can give 2/3 of a 3-ounce can for every pound of body weight on a daily basis. Give ½ of a 3-ounce can of kitten food for every pound of body weight per day.
Tony’s backpack can carry weight up to 22 but not more that that
If the variable n represents the total weight carried by tony
Then ; n less than or equal to (n=1+3+3b
=4+3b
Where b represents book
4+3b is less or equal to 22
3b is less or equal to 18
b is less or equal to 6
Therefore Tony’s backpack cannot carry more than 6 books
