A school bus can hold a maximum of 45 students. The correct inequality for this word problem is b ≤ 45. Why did I use ≤ not < in this problem?

This sign ≤ means greater than or equal to

but, this sign < means the number which is in the side is only greater

That why the sign ≤ is used

My this answer might be wrong , because in b ≤ 45 , I am confused from where the letter " b " came from .

$655.61 which is option c

step-by-step explanation:

price of house =   $146,000

initial rate = 3.5%

mortgaged paid in this = 3.5 % of $146,000

                                        =

                                        =$5110

the total years would be = 7

total mortgaged paid = 7 * $5110

                                      =$35770

remaining money = $146000-35770

                                =$110230

new mortgaged payment = 5 % of 110230

                                            =  

                                            =$655.61
