one french silk cheesecake = $7

one apple cheescake = $20

Step-by-step explanation:

Let the cost of one french silk cheesecake be represented by a

Let the cost of one apple cheescake be represented by b.

We are told that wilbur sold 13 french silk cheesecakes and 12 apple cheesecakes for a total of $331 . This can be written as:

13a + 12b = 331 equation i

Eugene sold 2 french silk cheesecakes and 3 apple cheesecakes for a total of $74. This can be written as:

2a + 3b = 74 equation ii

13a + 12b = 331 equation i

2a + 3b = 74 equation ii

Multiply equation i by 2

Multiply equation ii by 13

26a + 24b = 662 equation iii

26a + 39b = 962 equation iv

Subtract equation iv from iii

-15b = -300

b = 300/15

b = 20

The cost of one apple cheescake is $20.

From equation ii,

2a + 3b = 74

2a + 3(20) = 74

2a + 60 = 74

2a = 74 - 60

2a = 14

a = 14/2

a = 7

The cost of one french silk cheesecake is $7.

hope to and hope that my answer is brainliest.(follow me )

median is the value separating the higher half of a data sample, a population or probablity distribution from the lower half.

step-by-step explanation:

say you have 3,8,7,3,1,9,8 order them from lowest to highest

if orderd it would be 1,3,3,7,8,8,9 now you take away from the lowest and the highest until you end up in the middle.

so you would remove the 1 and 9 leaving you with 5 digits remaining

when you've reached the middle that would be your answer so in this case the answer is 7

if there were two numbers left say 7 and 5 you'd and them together so 12 then divide by 2 witch would equal 6 so the answer would be 6

good luck on that project hoped i you at all
