Molly and Arthur are taking their daughter Ginny on a roller coaster ride. For safety, they need to find their total weight befo

ruslelena [56]

Answer:

This is weirdly written, but let's try to solve it:

M is the mass of Molly

A is the mass of Arthur

G is the mass of Ginny.

We can represent the weight as:

(M + A) + G

or as:

A + (G + M)

the first situation shows that Molly and Arthur are weight together (this is why their weight is shown as only one), and then they weight Ginny alone.

The second situation shows that Arthur is weight alone, and Ginny and Molly are weight together (this is why their weight is written as only one)

lapo4ka [179]

Answer:

Selling price of hockey game set is $145.32 , markup price is $210.54 and profit is $96 .

Step-by-step explanation:

Let us assume that the selling price of hockey game set be x .

As given

Pyotr Tchaikovsky Sporting Goods operates on a 45% overhead based on the selling price, which results in an overhead of $65.34 on the newest version of an air hockey game set.

45% is written in the decimal form .

$= \frac{45}{100}$

= 0.45

Thus the equation becomes

0.45 × x = 65.34

0.45x = 65.34

$x = \frac{65.34}{0.45}$

x = 145.2

Therefore the selling price of the hockey game set is $145.2 .

Thus

Markup price = Selling price + Overhead Price

= $145.2 + $65.34

= $ 210.54

As given

If the air hockey game set costs Pyotr Tchaikovsky Sports $49.32 .

i.e Cost price of the hockey game set = $ 49.32

Profit = Selling price - Cost price

= 145.32 - 49.32

= $ 96

Therefore selling price of hockey game set is $145.32 , markup price is $210.54 and profit is $96 .
