Will mark needs $185 for a trip. she has $65 already and saves $12 a week that she earns babysitting. use the segment tool to plot a graph representing the amount of money jillian has saved from the time she begins saving until she has saved enough for the trip.(plot on graph with 2 points)

She needs 10 weeks to save enough for the trip.

Explanation:  Since,

According to the question, Initially she has $65 already.

And for a trip she needs $185. Also, she is saving 12 dollars per week.

Let, after x weeks she earns enough amount for  a trip from starting.

Thus, we can write,  65+12x=185

⇒12x=120⇒x=120/12=10

Therefore, after 10 weeks she can go to a trip.  

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!
