Jon needs to bulk-up for next AFL season. His energy needs t days after starting his weight gain program are given by E(t) = 350(80 + 0.15t)^0.8 - 120(80 + 0.15t) calcories/day. Find Jon's total energy needs over the first week of the program.
The Attempt at a Solution
I integrated the fuction above and interval was [0, 7] as the question says total energy needs over the first week. The answer i got was 14377 but the answer is 14400.
I think there is some problem with the interval or the value of C which i couldnt find.
Help me please~
