You can create and solve a proportion to get this answer.
Let x be the number of litters in 2500.
1. Write out proportion. 1/1000=x/2500
2. Cross Multiply. 1000x=2500
3. Divide by 1000 on each side. x=25
Answer:
The coordinates of the image of point A (2, -7) are A'(-1,-2).
Step-by-step explanation:
Note: The sign is missing between y and 5 in the rule of transitional.
Consider the rule of translation is

We need to find the image of point A (2, -7).
Substitute x=2 and y=-7 in the above rule.


Therefore, the coordinates of the image of point A (2, -7) are A'(-1,-2).
Answer: ($3.90)(12) - (2)($3.90) = 39.00
