Answer:

The charge for shovelling snow for 6 hour is 72 hours

Step-by-step explanation:

Given as :

The charge for shovelling snow for 2 \frac{1}{2} hours is $30

Let The charge  for shovelling snow for 6 hours = $ x

Now, Applying unitary method

∵ The charge for shovelling snow for 2 \frac{1}{2} hours = $30

or,  The charge for shovelling snow for \frac{5}{2} hour = $30

So, The charge for shovelling snow for 1 hour =  \frac{30×2}{5} hour

∴ The charge for shovelling snow for 6 hour =  \frac{30×2}{5} × 6 hours

I.e The charge for shovelling snow for 6 hour =  \frac{360}{5} hours

                                                                            = 72 hours

Hence The charge for shovelling snow for 6 hour is 72 hours  Answer

250 + 50=300

Is 2 125s and 1 50

Each 125 is 2.5

Kaylee and Olivia go to the movie theater and purchase refreshments for their friends.

The price of one bag of popcorn is $3.75

Step-by-step explanation:

Let,

x represent the cost of a bag of popcorn

y represent the cost of a drink.

According to given statement;

4x+12y=30      Eqn 1

x+6y=11.25      Eqn 2

Multplying Eqn 2 by 2

2(x+6y=11.25)\\2x+12y=22.50\ \ \ Eqn\ 3

Subtracting Eqn 3 from Eqn 1

(4x+12y)-(2x+12y)=30-22.50\\4x+12y-2x-12y=7.50\\2x=7.50

Dividing both sides by 2

\frac{2x}{2}=\frac{7.50}{2}\\x=3.75

4x+12y=30 and x+6y=11.25 can be used to find the price of one bag of popcorn and the price of one drink.

The price of one bag of popcorn is $3.75
