I would love some help please...At a private school in addition to tuition, students are charged for lab fees and supplies as shown:
Kgtn = $230
1st = $271
2nd= $300
4th = $340
6th = $369
7th = $385
Let f(n) be the per student charge (in dollars) for lab fees and supplies for nth grade, kindergarten is shown by n=0. A model for this situation is f(n)=228 4√n+1 Estimate for what grade the per student charge for lab fees and supplies is $394.

Best ResponseYou've already chosen the best response.0= 228 4√n+1) There is a space btwn 228 then a small raised 4 before the radical

Best ResponseYou've already chosen the best response.2oh ok f(n) = 394, solve for n \[\sqrt[4]{n+1} = \frac{394}{228}\] \[n+1 = (1.728)^{4}\] \[n=7.92\]
