Answer:
20 5/8 yd^2
Step-by-step explanation:
width = 3 3/4 yd
length = 5 1/2 yd
First change both measurements to fractions.
3 3/4 = 3 + 3/4 = 12/4 + 3/4 = 15/4
5 1/2 = 5 + 1/2 = 10/2 + 1/2 = 11/2
area = length * width
area = 15/4 yd * 11/2 yd
area = (15 * 11)/(4 * 2) yd^2
area = 165/8 yd^2
165/8 = 20 remainder 5
area = 20 5/8 yd^2

Take the amount of rows in the auditorium, 15, and multiply that by the number of new seats in each row, 3. You get 45. Now multiply the number of new seats, 45, by the cost of each seat, $74. You get $3,330.
<h2><u>In total, she will need $98.34 to pay all of the foods she plans to serve at the party.</u></h2>
All of the work:
<em>How to solve the amount of pizza she needs:</em>
20 x 3 = 60
60 divided by 10 = 6
<em>How to solve the amount of soda bottled needed:</em>
20 x 16 = 320
320 divided by 64 = 5
<em>How to solve the number of pans she needs:</em>
20(2 x 3) = 40 x 60
40 x 60 divided by 8 x 12 = 5
<h2>
THE COST CAN BE FOUND BY MULTIPLYING THE NUMBER OF THE ITEM NEEDED AND THE PRICE FOR EACH OF THE ITEM.</h2>
<em>Number of pizza she needs:6 pizza, costs $77.94</em>
<em>Number of soda bottles she needs:5 bottles, costs $8.45</em>
<em>Number of pans she needs:5 pans, costs $11.95</em>
<em>Add 77.94, 8.45, and 11.95 and get 98.34</em>
The y intercept is 9 and the unit rate is -7
So we plug these numbers in
y= -7x (the unit rate)+ 9 (y intercept)
y= -7x+9
