Answer:
226
Step-by-step explanation:
To find the percentage of a given value, firstly convert to a decimal by dividing by 100:
82 ÷ 100 = 0.82
Now, multiply this decimal by the number of tickets:
275 x 0.82 = 225.5
Because you can't sell half a ticket, round up.
This means the total of tickets they need to sell is 226.

Answer: he sold 9 pairs of dress shoes.
he sold 4 pairs of athletic shoes.
Step-by-step explanation:
Let x represent the number of pairs of dress shoes that he sells.
Let y represent the number of pairs of athletic shoes that he sells.
The total number of pairs of shoes that he sold in a day is 13. It means that
x + y = 13
The salesman receives a commission of $4 for every pair of dress shoes he sells. He is paid $3 for every pair of athletic shoes he sells. The commission that he got on that day was $48. It means that
4x + 3y = 48- - - - - - - - - - 1
Substituting x = 13 - y into equation 1, it becomes
4(13 - y) + 3y = 48
52 - 4y + 3y = 48
- 4y + 3y = 48 - 52
- y = - 4
y = 4
x = 13 - y = 13 - 4
x = 9
The slope for the line is 3/4
Answer:
$2.50
Step-by-step explanation:
Let the original monthly expenses be 'x'.
Given:
Reduced monthly expenses = $2.125
Reduction in monthly expenses = 15%
Therefore, remaining percentage of monthly expenses = 100 - 15 = 85%
Now, as per question:
Therefore, the original monthly expenses of Mr. Wood was $2.50.
Also, we can find his monthly income using the value of 'x'.
As per question, his monthly expenses is 80% of his income.
So, 80% of income = 2.5
Income = 
So, his monthly income is $ 3.125
