Question

You are waiting in line to buy tickets to see your favorite band. You know you will be waiting at least 80 minutes. You are taking some magazines that usually take you 20 minutes apiece to read.

a) What inequality symbol would be used to demonstrate this problem? (1 point)

b) Write and solve an inequality to determine how many magazines you will need to bring if you plan to read the entire time you wait

MEDAL WILL BE AWARDED

Answer 1

Let time waiting be T.

T >= 80 (time to wait is more or equal to 80)

Let magazine time reading be M

M >= 20 (time to read is more or equal to 20)

Thus,

M >= 20
4M >= 80 --- (1)

Sub (1) in T>= 80,
T >= 80 ----> T >= 4M

Answer 2

thank you
