Answer:
5. y = 200 + 350x
6. $ 1600
Step-by-step explanation:
5. Here, x represents the number of hours and y represents the total cost for x hours,
There is a charges of $200 plus $350 for each hour of use.
So, the fixed cost = $ 200,
∵ Additional cost for one hour = $ 350,
Then, the additional cost for x hours = 350x dollars,
Thus, the total cost = ( 200 + 350x ) dollars,
⇒ y = 200 + 350x
Which is the required equation.
6. for 4 hours,
x = 4,
Thus, the cost for 4 hours,
y = 200 + 350(4) = 200 + 1400 = $ 1600
