The Daily Info charges a fee of plus per week to run an ad. The People’s Paper charges per week. Write an inequality to represent the number of weeks an ad must run for the total cost at the Daily Info to be less expensive than the cost at the People’s Paper. Let w be the number of weeks the ad runs in the paper. A: 650 +80w<145w
B: 145+80w<650w
C:145+650w<80w
E:650+80w<145

Inequalities are used to represent unequal expressions.

The inequality is:

The given parameters are:

Daily Info

Fee = $650

Weekly Rate = 80

People's Paper

Weekly Rate = 145

Let the number of weeks be w.

So, the function that represents the total charges for Daily Info is:

The function that represents the total charges for People's Paper is:

If Daily Info is less expensive than People's Paper, then:

So, we have:

Hence, the inequality is:

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!
