Found a great explanation + 1105p = £11.05
Old price: 1,137.50 / 350 = 3.25
New price (at least): 1,500 / 350 = 4.3 (result is rounded)
#b. The equation y = 50x + 200 represents the total cost that the contractor will charge for x hours of work.
#c. (1, 250); (2, 300); (3, 350)
Answer: The correct answer is B because 0.7x=210, x=300
Step-by-step explanation:
210= 70% of the total distance to his grandfather's house, lets take that total distance for x.
So if:
210=0.7x
x=210/0.7
x=300
