.John has $40. He will use some of the money to buy books, and he wants to have at least $10 left to put in his savings account.
Crank

Answer:

The required inequality is 40-6b\leq 10.

Jhon can buy at most 5 books.

Step-by-step explanation:

Consider the provided information.

Part(A)

Let b represent the number of books John buys.

He wants at least $10 in his savings account which means if we subtract the cost of books from $40 we have at least $10 left.

40-6b\leq 10

The required inequality is 40-6b\leq 10.

Part(B)

40-6b\leq 10

-6b\leq 10-40

b \leq\frac{30}{6}

b\leq 5

Part(C):  Jhon can buy at most 5 books.

_______

   000

4320

_______

Therefore, there are 43200 minutes in a 30-day month.
