Answer:
200 pencils and 120 pens
Step-by-step explanation:
Let the number of pencils be x while pens be y.
Considering the cost of whole purchase then, we get the equation
0.5x+y=220
Considering the number of items bought, then the equation is
x-y=80
Adding the two equations then we have
1.5x=300
x=300/1.5=200
Consideeing that x-y=80 and x is 200 then
200-y=80
y=200-80=120
Therefore, the pencils were 200 and pens 120 pieces
Answer: $340
Step-by-step explanation:
To identify the cost of renting the boat for 30 hours, breakdown the 30hours into specific renting hours
i.e 30 hours = (7 hours + 10 hours + 13 hours)
Then calculate each of the renting cost based on the hour breakdown given above
- Since the Cost of renting a fishing boat is $25 per hour for the first 7 hours, then (25 x 7 hours = $175)
- For the $10 per hour for the next 10 hours, then (10 x 10 hours = $100)
- and for $5 per hour for any additional hours. (5 x 13 additional hours = $65)
Now, sum up all of the cost of the hourly breakdown
i.e 30 hours = (7 hours + 10 hours + 13 hours)
= $175 + $100 + $65
= $340
Thus, the cost of renting the boat for 30 hours is $340
