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

Answer:
8 to 18
Step-by-step explanation:
8 to 18
We are given with:
Average height of plants to be at least 73 inches
Three plants with heights of
70, 71, 72
The inequality that can be used to determine the possible heights of the fourth plant is:
(70 + 71 + 72 + x) / 4 ≥ 73
Solving for x
x ≥ 79
