12. Axis Training Studio offers three options for small group training. With Option A, members pay a $50 membership fee per month and $15 per training session. With Option B, members pay $150 per month for unlimited training sessions. With Option C, members pay $1500 per year for unlimited monthly training sessions. The following system represents the monthly rate for the three options, where x represents the number of training sessions attended each month. Which of the following are true? Select all that apply. * f(x)=50+15x
g(x)= 125
h(x)=150
The monthly rate of Option A is represented by f(x).
The monthy rate for Option C is represented by h(x).
If a member attends 6 training sessions during a given month, the monthly cost of Option B would be the best deal.
If a member attends 5 training sessions during a given month, the monthly cost of Option A would be equal to the monthly cost of Option C.

$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

multiply fractions:

divide:

mordancy.

ending amount = beginning amount / (2^n)

where "n" = number of half-lives (or elapsed time / half-life)

ending amount = 50 mg / (2 ^10 / 5.3)

ending amount = 50 mg / (2 ^ 1.8867924528)

ending amount = 50 m / 3.6981210597

ending amount = 13.5203794557 mg

or about 13.5 mg remain
