Answer:
y=3d+15
y intercept is 15
slope is 3
Step-by-step explanation:
to graph start at 15 on the y axis. then go up 3 points and over one point. keep doing this until you have a straight line.
15+3x=40
40-15=25
25/3=8.3 You could stay for about 8 days.
Step-by-step explanation:
all the steps of the problem
It will cost $36 to stay at the trip for a week and you can stay there for maximum 8 days.
We have a campsite that charges a rent of $15 fee to reserve the site, plus an extra $3 per day.
We have to find how much would it cost to camp for a week and if you had $40 to spend, how long could you stay there.
Assume that the maximum chocolates you can buy is ' x '. Then, we can find the maximum no chocolates by solving the inequality -
[tex]nx\leq m\\x\leq \frac{m}{n}[/tex]
Since there are 7 days in week and extra $15 are required to reserve the site, therefore - the total money required to stay a week long is :
M = 3 x 7 + 15 = $36
Let's assume that you can camp for maximum 'x' days. Then according to the question, the total money spent in staying x days at the trip should be less then or equal to 40. Hence -
[tex]3x +15\leq 40[/tex]
Subtract 15 on both sides, we get -
[tex]3x \leq 25\\x\leq 8.3\\or\\x\leq 8[/tex](approximate value)
You can stay for maximum 8 days.
Hence, it will cost $36 to stay at the trip for a week and you can stay there for maximum 8 days.
