Bill Board is trying to reduce his sodium intake to an average of 2300 mg. He records his sodium intake for 4 days. The amounts
sergiy2304 [10]

Answer:

His average for 4 days is 2542.5 mg

Intake of 5th day has to be less than 1330 mg

Explanation:

In order to find the average we take the sum of intakes for 4 day ans then divide it by total number of day which is 4 days.

Average = (2150 + 3005 + 2700 + 2315) / 4

Average = 10170/4

Average = 2542.5 mg

To find the 5th day intake such that average is below 2300 mg:

Let 5th day intake = x

We apply the same method to find the average by taking the sum of intakes for 5 days and then dividing the total with 5 days now. This average has to be less than 2300 mg therefore we use the following method:

(2150 + 3005 + 2700 + 2315 + x ) / 5 < 2300

2300 = (10170 + x)/ 5 < 2300

10170 + x < 11500

x < 11500 - 10170

x < 1330 mg
