<h3>#CMIIW</h3>
Mrs. Silverstein earned $105
A bakers dozen is equivalent to 13
91 cupcakes/13(a bakers dozen) = 7 boxes
7 boxes x $15 = $105 earned
So I labeled it as (1,7) as A, (-5,7) as B, and (-5,3) as C.So A is (0,5) and B as (-3,5) and then C as (-3,3).I think that would be correct.
Answer:
option C is correct
Step-by-step explanation:
We need to find the determinant.
= -1(7*9 - 3*9)-( -3)(4*9 - 3*3) -2(4*9 -7*3)
= -1(63-27) +3 (36 - 9) -2( 36- 21)
= -1(36)+3(27)-2(15)
= -36+81-30
= 15
Option C is correct
