The drama club spent $35 on decorations and $8.50 per person on food for a cast party. The total cost of the food
jenyasd209 [6]

Answer:

Option C) 27 people

Step-by-step explanation:

Let

x ----> the number of people

we know that

The cost of decorations ($35) plus the number of people (x) multiplied by the cost per person on food ($8.50) must be equal to $264.50

so

The linear equation that represent this situation is

35+8.50x=264.50

solve for x

Subtract 35 both sides

8.50x=264.50-35

8.50x=229.50

Divide by 8.50 both sides

x=229.50/8.50

x=27\ people

Which graph below shows the solutions for the linear inequality ys x-3?
liraira [26]

Answer:

Graph A.

Step-by-step explanation:

Given the inequality: y\leq \dfrac{1}{4}x-3

Since the sign is "less than or equal to", the line cannot be dotted. Therefore, Options C and D are incorrect.

Since the sign is a "less than" sign, the required region must be below the line. Therefore, the graph which shows the given inequality is Graph A.

A store marks up all of their merchandise by 70%. The floor price of a scarf is $117.25.
KiRa [710]

Answer:

  $68.97

Step-by-step explanation:

Markup is the difference between the cost of an item and the price at which it is sold:

  cost price + markup = selling price

Here, the markup is said to be 70%. The base for that percentage can be either the cost price or the selling price. The way this question is worded suggests the markup is 70% of the cost price.

So, we have ...

  cost price + 0.70 × cost price = selling price

or

  cost price × (1 + 0.70) = selling price

__

Then, to find the cost price, we can divide by its coefficient in this equation. Doing that gives ...

  cost price = (selling price)/1.70

  cost price = $117.25/1.70 = $68.97

The store's purchase price before the markup for this item was $68.97.
