Ms. Omar runs the school tennis club. She has a bin of tennis balls and rackets
For every 5 tennis balls in the bin, there are 3 tennis rackets. Draw a model to
show the ratio of tennis balls to tennis rackets
write the following ratios
tennis balls to tennis rackets
tennis balls to total pieces of tennis equipment

Draw a model ⇒ See the attached figure

Tennis balls to tennis rackets ⇒ 5 : 3

Tennis balls to total pieces of tennis equipment ⇒ 5 : 8

Step-by-step explanation:

Let the number of tennis balls ⇒ x

Let the number of tennis rackets ⇒ y

The general form represents the situation is ⇒ y = mx

Where m is the slope

Given: For every 5 tennis balls in the bin, there are 3 tennis rackets.

So, when x = 5 ⇒ y = 3

So, 3 = m * 5⇒ m = 3/5 = 0.6

∴ y = 0.6 x

See the attached figure which represents a model to show the ratio of tennis balls to tennis rackets.

Tennis balls to tennis rackets = 5 to 3 or  5 : 3

Total pieces of tennis equipment = 5 + 3 = 8

Tennis balls to total pieces of tennis equipment = 5 to 8 or 5 : 8

The percentage loss = 10.9375 %

Step-by-step explanation:

Let the cost price = x

Since the marked price is 18.75% above the cost price so the

Marked price = 1.1875 x

When a discount of 25% is allowed on the marked price , the selling price will be Rs. 1425

⇒ Marked price × 0.75 = 1425

⇒ Cost price × ( 1.1875 × 0.75 ) = 1425

⇒ Cost price × ( 0.890625 ) = 1425

⇒ Cost price = 1600

Selling price = 1425

So percentage loss =  × 100

% Loss =  × 100

% Loss = 10.9375 %
