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:
15+ 17+ 19+ 21+23
Step-by-step explanation:
consecutive odd integers, like 1, 3, 5, 7
consecutive even integers, like 2, 4, 6, 8
an integer is a <em><u>whole number</u></em>
2/3 is the answer because 6 in is the model and 4 ft is the actual
Answer:
8 and -2
Step-by-step explanation:
8 (-2) = -16
8 + (-2) = 6
