Hailey sold 20 tickets to the school play for a total of 225$.Early bird tickets were 10$ and regular priced tickets were 15$.Wr

dlinn [17]

Answer:

The system of equation are $\left \{ x+y=20} \atop {10x+15y=225}} \right.$

The number of early bird tickets are <u>15</u> and of regular tickets are <u>5</u>.

Step-by-step explanation:

Given,

Total number of tickets = 20

Total amount = $225

Solution,

Let the number of early bird tickets be 'x'.

And also let the number of regular tickets be 'y'.

Now total number of tickets is the sum of number of early bird tickets and number of regular tickets.

So framing in equation form, we get;

Total number of tickets = number of early bird tickets + number of regular tickets

$x+y=20\ \ \ \ equation\ 1$

Again, Total amount is the sum of number of early bird tickets multiplied with price of each ticket and number of regular tickets multiplied with price of each ticket.

So framing in equation form, we get;

$10x+15y=225\ \ \ \ \ equation\ 2$

Hence the system of equation are $\left \{ x+y=20} \atop {10x+15y=225}} \right.$

Now we solve the equation by multiplying equation 1 by 10, and get;

$10(x+y)=20\times10\\\\10x+10y=200\ \ \ \ equation\ 3$

Now subtracting equation 3 from equation 2, we get;

$(10x+15y)-(10x+10y)=225-200\\\\10x+15y-10x-10y=25\\\\5y=25\\\\y=\frac{25}{5}=5$

On substituting the value of 'y' in equation 1, we get;

$x+y=20\\\\x+5=20\\\\x=20-5=15$

Hence The number of early bird tickets are <u>15</u> and of regular tickets are <u>5</u>.

Help me pleasee i really need help

For ALL of these....use these formulas...

Finding Markup%

Markup=Selling Price-Cost

Markup%= $\frac{Markup}{Cost}*100$

1.) Recliner Chair. Cost=$61 Sell Price=$75.99

Markup= $75.99-$61
M=$14.99

Markup%= $\frac{14.99}{61} *100$

Markup%=24.5% (Markup less than 25%)

2.) Basket Ball. Cost=$23.75 Selling Price=$29.95

Markup= $29.95-$23.75
M=$6.20

Markup%= $\frac{6.20}{23.75} *100$

Markup%=26.1 (Markup greater than 25%)

3.) Necklace. Cost=$15 Selling Price=$19.25

Markup= $19.25-$15
M=$4.25

Markup%= $\frac{4.25}{15}*100$

Markup%=28.3 (Markup greater than 25%)

4.)Notepad. Cost=$1.19 Selling Price=$1.50

Markup=$1.50-$1.19
M=$0.31

Markup%= $\frac{0.31}{1.19}*100$

Markup%=26.1 (Markup greater than 25%)

5.)Speakers. Cost=$44.55 Selling Price=$54.99

Markup=$54.99-$44.55
M=$10.44

Markup%= $\frac{10.44}{44.55} *100$

Markup%=23.4 (Markup less than 25%)

6.) DVD. Cost=$10.80 Selling Price=$12.95

Markup=$12.95-$10.80
M=$2.15

Markup%= $\frac{2.15}{10.80}*100$

Markup%=19.9 (Markup less than 25%)

I hope this benefits other people in the future. :D

Explain how the expression 8.3√2+7.9√2 can be simplified using the distributive property.

IceJOKER [234]

Answer:

$\sqrt{2}(16.2)$

Step-by-step explanation:

The distributive property says that the answer of multiplying two numbers is the same as multiplying the first number by the sum or subtraction of two numbers that result in the second number.

What we have to do is to simpligy the ecuation, this mean, making it shorter.

First we take out the common term of the ecuation: $\sqrt{2}$ .

By distributive property $8.3\sqrt{2} +7.9\sqrt{2} =\sqrt{2}(8.3+7.9)$

then $\sqrt{2} (16.2)$ .
