Emily and Molly are selling pies for a school fundraiser. Customers can buy cherry pies and lemon pies. Emily sold 4 cherry pies and 1 lemon pie for a total of $30. Molly sold 8 cherry pies and 6 lemon pies for a total of $100. What is the cost for one cherry pie?

the cost of cherry= $5

the cost of lemon= $10

Step-by-step explanation:

let cherry pies be x

and lemon pie be y

total cost for Emily

4x+y=301

total cost for molly

8x+6y=1002

solve 1 and 2 simultaneously

4x+y=301

8x+6y=100---2

multiply 1 by 2

  8x+2y=603

 -8x+6y=100---2

0x-4y=-40

y=10

put y=10 in 1

4x+y=301

4x+10=301

4x=30-10

4x=20

x=20/4

x=5

the cost of cherry= $5

the cost of lemon= $10

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
