So the expression for total number of straws is: 15p+48b
Step-by-step explanation:
We know that:
Straws in a pack = 15
Straws in a box = 48
Here
p denotes the number of packs and b is the number of boxes.
The product of number of packs and number of straws in a pack will give us the total straws in packs
15*p = 15p
Similarly, the product of number of boxes and number of straws in a box will give us the total straws in box
48*b = 48b
The sum of both will give us the total number of straws
So the expression for total number of straws is: 15p+48b

Andy needs to subtract cost from the service revenue.
<h3>What does Andy need to subtract?</h3>
Revenue is the total income earned before any deductions are made. Net income is the total revenue less total expenses or cost.
Net income = total revenue - cost
For example, if a company sold 100 loaves of bread for $100 dollars. The cost of making the bread is $50. The revenue is $100 and the net income is $50 (100 - 50).

Step-by-step explanation:
The slope and the y intercept of the line on the graph is -1/4 and 1.
<h3>What is a Straight Line Function ?</h3>
A straight line function is what can be written in the form of
y =mx +c
where m is the slope and c is the intercept on y axis.
The intercept on the y axis , c = 1
at x = 4 , y=0
and at x = 0, y =1
The slope can be calculated as
y = mx+1
0 = 4m +1
m = -1/4
Therefore the slope and the y intercept of the line on the graph is -1/4 and 1.
