.Shanice and Micaela are selling cheesecakes for a school fundraiser. Customers can buy pecan
belka [17]

Answer:

Pecan cheesecake = $11

Strawberry cheesecake= $19

Step-by-step explanation:

To solve this, we will need to set up a system of equations:

Let's call "Pecan cheesecakes" 'x', and

"Strawberry cheesecakes" 'y'.

We can set up the equations once we have our variables:

276= 13x + 7y

295 = 13x +8y

We will need to subtract these equations from each other to get rid of the 'x' variable. This gives us:

295 = 13x+ 8y

        -

276 = 13x+ 7y

19 = y

Therefore, Strawberry cheesecakes cost $19. Plug this into an equation to get the value of 'x':

276= 13x + 7(19)

276 = 13x + 133

143 = 13x

x= $11.

Therefore, Pecan cheesecakes cost $11.
