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

Hannah has to make 25 gallons of punch for a potluck. The punch is made of soda and fruit drink. The cost of the soda is $1.79 p
Rus_ich [418]

Answer:

Hannah needs 10 gallons of soda and 15 gallons of fruit drink

Step-by-step explanation:

Let

x -----> the number of gallons of soda needed

y ----> the number of gallons of fruit drink needed

we know that

x+y=25 -----> equation A

1.79x+2.49y=2.21(25)

1.79x+2.49y=55.25 -----> equation B

Solve the system by graphing

Remember that the solution of the system of equations is the intersection point both graphs

The solution is the point (10,15)

see the attached figure

therefore

Hannah needs 10 gallons of soda and 15 gallons of fruit drink
