First, let's break down what this inequality means. 1,325 is the budget. 270 is the cost of the conference room. 26 is the number of people. That leaves x to be the amount you spend on lunch for each person.
So the budget is 1,325 and you are trying to find a value to fit into that price range which means it has to be less than or equal to 1,325. To do that, you already know that the conference room will cost 270 no matter what so you have to add that to the the amount for lunch which means you are subtracting it from the total cost of the budget.
Then you divide what's left of the budget by the number of people.
That leaves you with x which is the amount you can spend on lunch per person.
I finished it off for you and got
which is the same as
That means you can spend less than or equal to in other words at most $40.58 on lunch per person.
Answer:
$12
Step-by-step explanation:
Lola has x.
Mary-Ann has 2 1/3 times Lola's amount, so Mary-Ann has (2 1/3)x.
Mary-Ann has $28.
(2 1/3)x = 28
7/3 x = 28
Multiply both sides by 3/7.
x = 28 * 3/7
x = 12
Lola has $12.

Step-by-step explanation:
The common difference d of an arithmetic sequence is
d = - = -
Substitute in values and solve for k, that is
5k - 1 - 2k = 6k + 2 - (5k - 1)
3k - 1 = 6k + 2 - 5k + 1
3k - 1 = k + 3 ( subtract k from both sides )
2k - 1 = 3 ( add 1 to both sides )
2k = 4 ⇒ k = 2
--------------------------------------------------------
The n th term of an arithmetic sequence is
= + (n - 1)d
= 2k = 2 × 2 = 4 and
d = 5k - 1 - 2k = 3k - 1 = (3 × 2) - 1 = 5
Hence
= 4 + (7 × 5) = 4 + 35 = 39
