Solve the inequality and show on a number line

(picture included below)

Step-by-step explanation:

I cant show a number line so i'll do my best to explain how its graphed.

15) x - 1 < 15

add 1 to both sides:

x < 16

Because it is less than, rather than less than or equal to, it's graphed with an open circle (not filled in) on 16, and everything less than 16 highlighted

16) 2(y + 1) - 2 ≥ 12

distribute the 2:

2y + 2 - 2 ≥ 12

combine like terms

2y ≥ 12

isolate y:

y ≥ 6

This one is greater than or equal to, so it's graphed with a closed circle (filled in) and everything above 6 highlighted

if the probability is 1/12, 75 people will receive a $25 gift card

step-by-step explanation:

the answer is d
