Answer:
255
Step-by-step explanation:
total cost paid = fixed cost + total variable cost
total variable cost = distance travelled x variable cost per unit
two equations can be derived from the question
a + 10b = 105 equation 1
a + 15b = 155 equation 2
a = fixed cost
b = variable cost per unit
Subtract equation 1 from 2
5b = 50
b = 10
Substitute for b in equation 1
a + 10(10) = 105
a = 105 - 100 = 5
a = 5
cost of travelling a distance of 25km
5 + 10(25) = 255

Answer:
Step-by-step explanation:
1. Rotate 90° counterclockwise about the origin and then translate 5 units left.
2. Reflect across the y-axis and then rotate clockwise 180° about the origin.
- Incorrect, this ends up in the first quadrant, additional translation is required
3. Rotate 180° about the origin.
- Incorrect, additional translation is required followed by rotation.
4. Rotate 90° clockwise about the origin and then translate 1 unit right and 5 units up.
