Answer:
The highest number of pens = 120
The highest number of pencils = 600
Step-by-step explanation:
Let x denote the number of pens
Let y represent the number of pencils.
Each pen requires $0.75
Therefore, the total cost for x pens is 0.75 x
Each pencil costs $0.15.
Thus, the total cost for y pencils is 0.15y
The glee club has a total budget of $90 for these supplies.
Consequently,
Thus, the equation explaining how many pens and pencils can be purchased by the club is
Part A)
Part B) Determine the maximum quantity of each writing instrument the club can acquire.
Setting y = 0 gives:
The maximum number of pens = 120
Now, setting x = 0 yields:

Answer:
y = 22.5 - 0.2t
Step-by-step explanation:
The given information includes;
total weight of the candle, n = 22.5 ounces
Candle burn rate, R = 1 ounce every 5 hours
The remaining candle amount is calculated as initial amount minus burnt amount
Let the remaining amount be y
y = 22.5 - 0.2t
where;
t represents the time the candle has been burning
Therefore, the equation for the leftover candle is expressed as;
y = 22.5 - 0.2t
