Answer:
the answer is 3
Step-by-step explanation:
Your total expense would be 35$ because 25+10=35 and then since you are talking about money you add the money sign. Your answer would be 35$
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
