A Verizon smartphone plan charges an $80 service fee and then $45 per month. Which of the following expressions models the total money spent for this plan after m months?

$45m+$80= total money spent

Step-by-step explanation:

the $45 is multiplied by the number of months that the plan is used becuase that is the amount that must be paid per month, and you add the $80 that only needs to be paid once.

I hope that helps!

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!
