Question 570103: A basket contains many apples and the apples are divided among six people. One third, one fourth, one eigth, and one fith of the apples are given to the first four people, respectively. The fith person gets ten apples and the sixth person gets one apple. Find the original number of apples in the basket.
I tried the following: Let A = Original number of apples
x = number of apples given
A= 1/3x + 1/4x + 1/8x + 1/5x + 10 + 1
Next I determined the LCD was 120
A = 40/120x + 30/120 + 15/120x + 24/120x + 10 +1
A = (109/120x + 11)*120
120A = 109x + 11
120A - 11 = 109x
120A - 11/109 = x
If I left the x out of the fractions then I got the following
120A = 109 +11
120A = 120
Please solve, show work and show me what I'm doing wrong.
Thanks,
Norm

Question 572864: Here is the word problem I am trying to write an equation for:
" Mike received 73%, 71%, 79% and 75% on his first four math tests. What grade on his fifth test would allow him to make an average of at least 75%? Assume the test scores are whole numbers."
Here is what I have tried so far:
Let X represent fifth test score
(73 +71+79+75 + X)/5 = 75
(298 + X)/5 = 75
59.6 + 1/5X = 75
X = (75 - 59.6)/5
X = 3.08

I know this is not correct but I am not sure what is wrong with my equation. Any help showing me how to set up the right equation would really help me. thanks
