Answer:
9 tables (see below)
Step-by-step explanation:
Let t represent the number of table sales required to meet revenue requirements. The total of sales for the day must be ...
7(200) +t(800) ≥ 8000
800t ≥ 6600 . . . . . . . . . . subtract 1400
t ≥ 8.25
If additional sales are limited to tables, the store must sell at least 9 tables. The revenue goal can also be met by selling 1 chair and 8 tables. (A chair brings in 0.25 times the revenue of a table.)
If the store sells 5 more chairs, it only needs to sell 7 tables. (This combination will result in 19 pieces being sold.)
You have to distribute the 4 to the numbers in the parenthesese. So 4 times 3x which is 12x and 4 times 5 which is 20 so now you get 12x plus 20 equals 8. Now you have to subtract 20 from 8 which is -12 so now you have 12x=-12 now divide the 12 from x and 12 from -12 and so now you have x=-1

Factoring is a common mathematical process used to break down the factors, or numbers, that multiply together to form another number. Some numbers have multiple factors.
<u>Explanation:</u>
Factoring polynomials involves breaking up a polynomial into simpler terms (the factors) such that when the terms are multiplied together they equal the original polynomial. Factoring helps solve complex equations so they are easier to work with. Factoring polynomials includes: Finding the greatest common factor.
Factoring (called "Factorizing" in the UK) is the process of finding the factors: Factoring: Finding what to multiply together to get an expression. It is like "splitting" an expression into a multiplication of simpler expressions.
$5.50 x 2 is $11.00
$2.50 x 2 is $5.00
$11 plus $5 is $16
