Well, you would need to compensate for the cost of the banquet hall adding an addition $700 to the goal of $1000.

If you need to raise at least $1700 you can write this inequality.

Let x represent the number of tickets sold.

15x≥1700

x≥ 114 (rounded to the nearest whole number because you can't sell half a ticket)

So, at least 114 tickets need to be sold.

Answer:

Grades to be scored in 3rd exam = 88

Step-by-step explanation:

Given that average of 3 numbers is 85.

First two numbers are 81 and 86.

To find:

3rd number so that average is 85

Solution:

Let the third number = $x$

Formula for average is:

$Average = \dfrac{Sum\ of\ numbers}{Total\ count\ of\ numbers}$

Here, sum of numbers = $81+86+x =167+x$

Total count of numbers = 3

$85 = \dfrac{167+x}{3}\\\Rightarrow x=255-167\\\Rightarrow \bold{x=88}$

Grades to be scored in 3rd exam = 88
