Answer:
Booster club purchased 5 pies.
Step-by-step explanation:
Let the number of pies purchased by booster club be represented by n. The school also donated 3 pies to sell.
So that,
Total number of pies = n + 3
Given that there was 64 pieces of pies to sell after cutting each pie into 8 pieces.
Thus,
8( n + 3) = 64
8n + 24 = 64
8n = 64 - 24
8n = 40
Divide both sides by 8 to have,
n = 5
The number of pies purchased by booster club is 5.
5-(-4)
5 + 4 = 9
exceeds by 9
Step-by-step explanation:
a1 = 27
r = -9/27 = -⅓
the formula :
an = a1. r^(n-1)
= 27. (-⅓)^(n-1)
= 3³(-3`¹)^(n-1)
= 3³(-3)^(1-n)
