Answer:
Cost for skii: J(x) = 30x + 7
Cost for beach chair: B(x) = 5x + 3
=> Total cost = J(x) + B(x) = 30x + 7 + 5x + 3 = 35x + 10
=> Option C is correct.
Hope this helps!

Answer:800-300
Step-by-step explanation:
since there is a 1 after the 8 it would go down to 800 and there is a 8 after the 2 so it would go up to 300

rate = 95/ 1500 = 0.0633333
rate = 6.33%
Answer:

Step-by-step explanation:
1. The situation after 15 min:
(a) Distance travelled by simulated biker:
15 min =¼ h

(b) Distance travelled by Julian
Julian is 2¼ km behind the biker. The distance he has travelled is (5 - 2¼) km
5 - 2¼ = 5 - ⁹/₄ = ²⁰/₄ - ⁹/₄ = ¹¹/₄ = 2¾
Julian has travelled 2¾ km in ¼ h.
2. Julian's average speed

i believe it is 19 if im wrong sorry
