Step-by-step explanation:
Given that:
Supplies of the lemonade bought at price = $50
Money paid per day to setup lemonade stand at the park = $5
To find:
Equation of her total cost.
Solution:
Let the number of days =
Per day cost of setting up the lemonade stand is given as $5.
If the number of days are , then the cost of days can be found by multiplying the per day cost with the number of days.
Therefore, the expression for cost for number of days =
Total cost for number of days can be found by adding the cost of supplies and cost for number of days for setting up the stand:
Answer:
w+2r>12
w+2r<20
Step-by-step explanation:
Walking :
Speed = 3 mph
Time of walking = w hrs (given)
Total distance covered = Speed x time
D1=3w
Running
Speed=6 mph
Time of running = r hrs ( Given)
Total distance covered = Speed x time
D2 = 6r
The condition says that
Total distance > 36 miles
That is
D1+D2>36
3w+6r>36
Dividing both sides by 3 we get
w+2r>12
Also
D1+D2<60
3w+6r<60
w+2r<20
Hence the system of inequations representing the above condition are
w+2r>12
w+2r<20
