at lunch, kira eats either a burrito containing 490 milligrams of sodium or a peanut butter sandwich containing 700 milligrams of sodium. her doctor told her to reduce her sodium to no more than 4,000 milligrams per week. which inequality represents x, the number of microwave burritos, and y, the number of peanut butter sandwiches, she can eat each week?\no 490x + 700y < 4000\no 490x + 700y ≤ 4000\no 490x + 700y > 4000\no 490x + 700y ≥ 4000

Answer

Explanation:

Step1: Calculate total sodium intake

The sodium in $x$ burritos is $490x$ (since each burrito has 490 mg of sodium) and in $y$ peanut - butter sandwiches is $700y$ (since each sandwich has 700 mg of sodium). So the total sodium intake is $490x + 700y$.

Step2: Set up the inequality

Her doctor told her to reduce her sodium to no more than 4000 milligrams per week. "No more than" means less than or equal to. So the inequality is $490x+700y\leq4000$.

Answer:

B. $490x + 700y\leq4000$
