The cost for plan A and plan B at a discount warehouse is $57 and $153 respectively.
<h3>Equation</h3>
Plan A:
Manufacturer's recommended list price = 90%
= 90% × 30
= 0.9 × 30
= $27
Total cost of plan A = $30 + $27
= $57
Plan B:
Manufacturer's recommended list price = 70%
= 70% × 90
= 0.7 × 90
= $63
Total cost of plan B = $90 + $63
= $153
Therefore, the cost for plan A and plan B at a discount warehouse is $57 and $153 respectively.

Answer:
Third option is correct. Scale factor 3 ; enlargement.
Step-by-step explanation:
It is given that the figure A'B'C'D' is a dilation of figure ABCD.
We know that after dilation the corresponding sides of image and preimage are in the same proportion.
The image of AD is A'D'.
From the figure it is noticed that the A(-1,2), D(-1,-1), A'(-3,6) and D'(-3,-3).
Distance formula is



Scale factor is constant which represents the relation between image and preimage.



Therefore the scale factor is 3.
If k>0 it means enlargement and if k<0 it means reduction. Therefore third option is correct.
