Aparty rental company has chairs and tables for rent. the total cost to rent 5 chairs and 3 tables is $30. the total cost to rent 2 chairs and 6 tables is $42. what is the cost to rent each chair and each table?

Step-by-step explanation:

Let the rent one chair is C and the rent for one table is T.

As per the given condition,

= 30................(1)

= 42................(2)

Multiplying the equation (1) with 2 and (2) with 5, then subtracting, we get = 210 - 60

= 150

T =

T = 6.25

Putting the value of T in equation (1) we get,

= 30

= 30 - 3 \times6.25[/tex]

= 11.25

C =

C = 2.25

hello from mrbilldoesmath!

answer:

a(n) - a(n-1) -3

discussion:

this ones a bit interesting. given a(n) = 5 - 3n consider this:

a(n-1) = 5 - 3(n-1)

          = (5 - 3n) + 3             => but a(n) = 5 - 3n, the first term

          = a(n)   + 3                 => subtract 3 from both sides

a(n-1) -3 = a(n)  

or

a(n) - a(n-1) -3
