Answer:
(b) 6 in × 8 in
Step-by-step explanation:
You have a poster that is 24 in by 32 in after enlargement of a photo by a factor of 4, and you want to know the original photo dimensions.
Enlargement
The factor of 4 enlargement means each poster dimension is 4 times the original photo dimension. The photo dimensions can be found by dividing poster dimensions by 4:
photo = poster/4
photo = (24 in)/4 by (32 in)/4 = 6 in by 8 in
The dimensions of the original photo are 6 inches by 8 inches.
