Question 1083575
 buy 190 kiwis which cost $66.50. I sell each kiwi 55 cents.
 What is the minimum number of kiwis that i need to sell in order to obtain a profit not less than $20?
:
let n = no. of kiwis sold to make $20
:
.55n = total revenue of the kiwis sold
:
.55n - 66.50 = 20
.55n = 20 + 66.50
.55n = 86.50
n = 86.50/.55n 
n = 157.3 ~ 158 need be sold to make at least $20
