frankie has an avg of 57% and he has 2 test left worth 5% each and 1 assigment worth 1% and 2 assigment both 3% how much would he need to bring his avg to 87?

(i hear this questions has been answered can someone either direct me to where it has been answered or answer it please)

As far as I can see, this question has not been adequately answered.

You haven't provided enough information -- such as the total points nor the points alloted to each test and assignment -- to determine an answer.

say that they are all out of 60 marks

To calculate how much Frankie would need to bring his average to 87%, we need to consider the weights of the remaining assessments.

First, let's calculate Frankie's current weighted average by multiplying his average (57%) by its weight (94%). This gives us:
Current weighted average = 57% * 94% = 0.57 * 0.94 = 0.5358 (rounded to four decimal places)

Now, we need to calculate the remaining weighted average to see how much Frankie would need from the remaining assessments. Let's denote the final weighted average as "x". We can set up the following equation:

(Current weighted average * current weight) + (Remaining weighted average * remaining weight) = Desired average * total weight

Plugging in the known values, the equation becomes:

(0.5358 * 94%) + (Remaining weighted average * 6%) = 87% * 100%

Simplifying the equation gives us:

(0.5358 * 0.94) + (Remaining weighted average * 0.06) = 0.87

Now, we can solve for the remaining weighted average:

0.503652 + 0.06 * Remaining weighted average = 0.87

0.06 * Remaining weighted average = 0.87 - 0.503652

0.06 * Remaining weighted average = 0.366348

Remaining weighted average = 0.366348 / 0.06

Remaining weighted average = 6.1058 (rounded to four decimal places)

Therefore, Frankie would need a remaining weighted average of approximately 6.1058% to bring his overall average to 87%.
