Following the guidelines of the food and drug administration, dale tries to eat at least 5 servings of fruit each day. for the first six days of one week, she had 4, 5, 3, 5, 4, and 4 servings. how many servings of fruit should dale eat on saturday to average at least 5 servings per day for the week?

So then the value for Saturday should be equal or higher to 10 servings per day in order to have an average of 5 or higher.

Step-by-step explanation:

First we can begin finding the original average for the first 6 days of the week. We assume that the week start at Sunday, and we have data for Sunday, Monday, Tuesday, Wednesday, Thrusday, Friday. And we can find the average like this:

And for this case we have the original average under the goal of 5, so we need to find a value x, such that the final average taking in count the 7 days of the week would be 5.

So we can nultiply both sides by 7 and we got:

And then solving for x we got:

So then the value for Saturday should be equal or higher to 10 servings per day in order to have an average of 5 or higher.
