Zoe has $545 saved in the bank. She earns $80 per week working after school. Which function can be used to find y, the amount of money Zoe will have saved at the end of x weeks? A. y= -80x + 545
B. y= 45x + 545
C. y= 80x + 545
D. y= 545x + 80

Option: D. y= 545x + 80

Step-by-step explanation:

Linear Modeling

The initial amount in the bank is $545. Each week an amount of $80 is earned. In x weeks, Zoe will have earned 80x.

Thus, the total savings in x weeks are:

y = 545 + 80x

Option: D. y= 545x + 80

a) one student is chosen from classroom a, then a student is chosen from classroom b.  

step-by-step explanation:

independent events are ones in which the probability of one event does not affect the probability of the second event.

one student is chosen from classroom a; this does not affect the chances of choosing a student from classroom b.   this makes these independent events.

when one card is chosen from a standard deck and then set aside before a second card is chosen, the probability of the second card being chosen changes.   this makes them dependent events.

when one student is chosen from classroom a and then a second student is chosen from classroom a, the probability of choosing the second student changes.   this makes them dependent events.

when a letter is chosen from the alphabet and then a second letter is chosen, the probability of choosing the second letter changes.   this makes them dependent events.
