The cost of the  $0.5 per cookies and $1.25 per brownie.

Option (A) is correct.

Step-by-step explanation:

Let us assume that the cost of the cookies =x

Let us assume that the cost of the brownie = y

As given

Sara is selling cookies and brownies as a fundraiser for the school band.

She charges $2.25 for two cookies and one brownie.

Than the equation becomes

2x + y = 2.25

She charges $5.75 for four cookies and three brownies.

4x + 3y = 5.75

Than two equation are

2x + y = 2.25  and 4x + 3y = 5.75

Multiply 2x + y = 2.25  by 3 and subtracted from 4x + 3y = 5.75

4x - 6x + 3y - 3y = 5.75 - 6.75

-2x = - 1

2x = 1

x = $0.5

Put in the equation 2x + y = 2.25

2 × 0.5 + y = 2.25

1 + y = 2.25

y = 2.25 - 1

y = $1.25

Therefore the cost of the  $0.5 per cookies and $1.25 per brownie.

Option (A) is correct.

option: d is the correct answer.

d) none of the above.

step-by-step explanation:

clearly from the figure attached to the question we could see that there is no shape given. hence without any shape given in the figure and after rotation we can't obtained a square pyramid.

since, to obtain a image we need a proper figure of the pre-image so that it can be transformed.

hence, the correct answer is:

d) none of the above.

step-by-step explanation:

i don't know, but that looks pretty bad. my school passed us unless we failed in all the subjects, but idk abt ur school's rules.
