Before a bowler rolls her first ball, 10 pins are standing. The number of pins that will be left standing, y, is a function of the number of pins she knocks down. What is the domain of this function?

• { 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 }

• { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 }

• y ≤ 10, integers

• 0 ≤ y ≤ 10, real numbers

Erika has a savings account that has $125. She starts saving $5 per week for a new iPhone. Write a function to represent the total amount Erika has in her savings account. How much money will she has after 10 weeks?

• y = 125x + 5

• y = 5x + 125

• y = 125x - 5

• y = 5x - 125
