Which situation can be modeled by the inequality 5 + 10w ≥ 45?
A. You start with $5 and save $10 a week until you have at least $45.
B. You start with 5 baseball cards and purchase 10 cards every week until you have at most 45 cards.
C. You start with 5 water bottles and purchase cases of 10 water bottles each until you have a total of 45 water bottles.
D. You spend $5 plus $10 per week until you have less than $45.

The situation can be modeled by the inequality is:

You start with $5 and save $10 a week until you have at least $45 ⇒ A

Step-by-step explanation:

The form of the linear equation is y = m x  + b, where

∵ 5 + 10 w ≥ 45

∵ b + m x ≥ a

∴ b = 5 , m = 10 , ≥ is at least and a = 45

That means:

→ The initial value is 5

→ The rate of change is 10

→ The value is at least 45

∴ You start with $5

∴ You save $10 per week

∴ You have at least $45

The situation can be modeled by the inequality is:

You start with $5 and save $10 a week until you have at least $45.

make sure you have version 2.50

try looking in the very back of the book : )

thats not a system of equations, that is a solution
