CAN SOMEONE HELP ME PLS ? Jason purchased a cell phone on sale for $100. He will pay a $25 monthly service for the line. Write an equation for this scenario. Is this a proportional relationship?

Step-by-step explanation:

y = 25x +100

y- is the total money spent on the phone

x-is the number of months you had service

the relationship between x and y is proportional ( if x grows, y grows)

For example: after 2 months you would had payed $100 for the phone + the $25 each of the 2 months. y= 25*2 +100 = $150

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!
