Answer:
D 4/10 = 2/x
Step-by-step explanation:
2/x represents the ratio of the man's height to the tree's height. The appropriate proportion will be one that ratios the man's shadow (4 m) to the tree's shadow (6+4=10 m).
The correct proportion is ...
4/10 = 2/x
60 square feet for 287 = 287/60 = 4.78 per square foot
so ur equation would be : y = 4.78x + 80....where x is the number of square feet and y is the total cost
