What is a word problem?A word problem is a verbal description of a problem situation. It consists of few sentences describing a 'real-life' scenario where a problem needs to be solved by way of a mathematical calculation.
For the given situation,
Grill rental fee = $150
Charge per person for less than 100 students = $5
Charge per person for 100 students or more = $4.25
Total number of students = 125
The total cost for 125 students is
⇒ [tex][150+5(99)]+[150+4.25(26)][/tex]
⇒ [tex][150+495]+[150+110.5][/tex]
⇒ [tex][645]+[260.5][/tex]
⇒ [tex]905.5[/tex]
Hence we can conclude that the total cost for 125 students is $905.5.

A company sells fruit cups in packs of 4. The packs currently weigh 20 oz. The company plans to reduce the weight of each cup by n oz. The expression 20 – 4n represents the new weight, in ounces, of a pack of fruit cups. Rewrite the expression for the new weight as a product of two factors.
Answer:
4 ( 5 - n )
Step-by-step explanation:
The expression:
20 – 4n
Task: Rewrite the expression for the new weight as a product of two factors.
To do this we simply have to find the highest common factor (HCF) between 20 and 4n
20 = 4 * 5
4n = 4 * n
The HCF = 4
Expressing as a product of two factors;
4 ( 5 - n )

A 135.8 foot wire is attached to the top of the tower. If the wire is attached to the ground 30 feet from the bottom of the tower, then what angle does the wire make with the ground?
Answer:
77.23°
Step-by-step explanation:
Given that,
A 135.8 foot wire is attached to the top of the tower.
The wire is attached to the ground 30 feet from the bottom of the tower.
It means,
If we consider a triangle such that hypotenuse is 135.8 foot and base is 30 feet, it means we can use the trigonometry as follows :
[tex]\cos\theta=\dfrac{B}{H}\\\\\cos\theta=\dfrac{30}{135.8}\\\\\theta=77.23^{\circ}[/tex]
So, the angle the wire make with the ground is equal to 77.23°.
