Answer 1

490x + 700y < = 4000 (thats less then or equal)

Answer 2

Answer:

The required inequality is $490x+700y \leq 4,000$.  

Step-by-step explanation:

Consider the provided information.

Kira eats either a burrito containing 490 milligrams of sodium or a peanut butter sandwich containing 700 milligrams of sodium.

let x is the number of burritos and y is the number of peanut butter sandwiches.

If she takes x numbers of burritos which containing 490 milligrams of sodium or y numbers of peanut butter sandwich which containing 700 milligrams of sodium. This can be written as:

490x+700y

Her doctor told her to reduce her sodium to no more than 4,000 milligrams per week.

No more than 4,000 milligrams of sodium means, she can take less than or equal to 4,000 milligrams of sodium.

The inequality sign used for less than or equal to is "≤".

Therefore, the required inequality is $490x+700y \leq 4,000$.
