711 of the customers were women. Within five minutes, 69 more women and 31 more men entered the supermarkets. As a result, there were 95 more women than men. How many customers were there altogether in the end?
|
Women |
Men |
Before |
7 u |
4 u |
Change |
+ 69 |
+ 31 |
After |
7 u + 69 |
4 u + 31 |
If there are another 95 men in the end, the number of men and women will be the same.
7 u + 69 = 4 u + 31 + 95
7 u - 4 u = 126 - 69
3 u = 57
1 u = 57 ÷ 3 = 19
Number of customers in the end
= 7 u + 69 + 4 u + 31
= 11 u + 100
= 11 x 19 + 100
= 209 + 100
= 309
Answer(s): 309
