April and alex are saving money to buy new phones. each friend starts with some money and saves a specific amount each week. alex wrote an equation to show the total, y, she has saved at the end of each week, x. y = 20x + 125 april made a graph to show the total he has saved at the end of each week.. compare the amount that each friend has when both friends start saving. select the correct answer from the drop-down menu to complete the statement. alex starts with $ and april starts with $.

Step-by-step explanation:

Givens:

Now, to know the initial amount of money each person started from, we have to look for initial conditions.

In the graph, we observe that the linear relation starts at , that means April started with $100, because refer to money, and to weeks.

On the other hand, the initial condition of Alex is when , that is, at the moment where time didn't start yet, that is, in the moment he began to save. So,

Therefore, Alex started with $125, that's his initial condition

According to these results, Alex starts with $125 and April with $100.

ummm seems that u didnt post the attachement !

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!
