What did you scan, it’s not letting me see it lol
Answer:
(4, 0)
Step-by-step explanation:
3x + 4y = 12
2x - y = 8
8x - 4y = 32
11x = 44
x = 4
y = 0
6.473
^ This is the 2nd decimal place.
Look at the number after it, if it's 5 or more, round up, if it's 4 or less round down.
The number is 3, so we round down to 6.47.
At 3 hours both Jacaranda and Wiles would have the same cost
Let y represent the total charges by Jacaranda and x represent the number of hours. Hence:
y = 12x + 40
Let z represent the total charges by wiles and x represent the number of hours. Hence:
z = 22x + 10
Since they are to have the same cost, hence:
y = z
12x + 40 = 22x + 10
10x = 30
x = 3 hours
Therefore at 3 hours both Jacaranda and Wiles would have the same cost.
