We have to evaluate the summation of (3n+2), with n ranging from 1 to 14. Let's write all the terms of the sum for each value of n:
n=1:
n=2:
n=3:
n=4:
n=5:
n=6:
n=7:
n=8:
n=9:
n=10:
n=11:
n=12:
n=13:
n=14:
Now, let's sum all the terms together, and we get:
Answer:
25% is the answer because 25 x 4 = 100% and 20x4= 80
Answer:
that is based on luck u could get 5 everytime or none, depends on what roll
1/3 * 420 = amount of t-shirts sold in the morning
1/3 * 420 = 420/3 = 140 t-shirts
140 t-shirts were sold, so remaining is 420 - 140
420 - 140 = 280 remaining t-shirts
4/7 * 280 = amount of t-shirts sold in the afternoon
4/7 * 280 = (280/7) * 4 = 40 * 4 = 160 t-shirts
160 t-shirts were sold, so remaining is 280 - 160
the remaining t-shirts = 120 t-shirts
120 t-shirts are left to sell at the end of the day
Thanks. I’m not struggling or anything but thanks for the kind words.
