A party rental company has chairs and tables for rent. The total cost to rent 4 chairs and 8 tables is $89 . The total cost to r

puteri [66]

Let C = cost to rent each chairLet T = cost to rent each table

4C + 8T = 73
2C + 3T = 28
Multiply the 2nd equation by (-2) and then add the equations together

4C + 8T = 73
-4C - 6T = -56
2T = 17T = 17/2 = 8.5

Plug this in to the 1st equation to solve for C
4C + 8(17/2) = 73
4C + 68 = 73
4C = 5C = 5/4 = 1.25
So the cost to rent each chair is $1.25 and the cost to rent each table is $8.50

Natasha_Volkova [10]

The answer is $36.

B - budget
So the calculation is as following:
$B= \frac{1}{2}B + 12.27 + \frac{3.82}{ \frac{2}{3} } = \frac{1}{2}B + 12.27 + \frac{3.82*3}{2}= \frac{1}{2}B + 12.27 +5.73$
$B= \frac{1}{2} B + 18$
$B- \frac{1}{2}B = 18$
$\frac{1}{2}B = 18$
$B = 18*2=36$
