I think the question is asking for the cost (C) when we already know that the sell price (S) is $24
So C+M=S
C+0.45C=24
1.45C=24
C=16.5516
And the answer is $16 and 55 cents

3(2a + 1) = -5(a + 6)

Lemur [1.5K]

3(2a+1)=-5(a+6)
First expand the brackets.
6a+3=-5a-30
Now add 5a to both sides.
11a+3=-30
Then subtract 3 from both sides.
11a=-33
Finally divide both sides by 11.
a=- 33/11
=-3

Dilation about the origin multiplies every coordinate by the scale factor.

C' = 4(-5, 2) = (-20, 8)

A' = 4(-4, 4) = (-16, 16)

T' = 4(-1, 2) = (-4, 8)
