Answer:

Wyatt participated in 3 games and enjoyed 6 rides

Step-by-step explanation:

Let x represent the number of games

And let y represent the number of rides

Each game costs $1.25

Each ride costs $2.75

The total expenses incurred by Wyatt amounted to $20.25

Thus, the equation becomes: x1.25 + y2.75 = 20.25..... Equation 1

The number of rides he enjoyed is double the games he competed in

Y = 2x... Equation 2

By substituting the value of y into equation 1

x1.25 + y2.75 = 20.25

x1.25 + 2(x)2.75 = 20.25

x1.25 + x5.5 = 20.25

x6.75= 20.25

x= 20.25/6.75

X= 3

Y= 2x

Y= 2(3)

Y= 6

Thus, Wyatt participated in 3 games and enjoyed 6 rides

We can summarize that

By applying the law of cosines: 

c² = a² + b² - 2abcos(C) 

where: 

a,b, and c represent the triangle's sides and C denotes the angle opposing side c.

Let us assign:

a=170 miles

b=200 miles

c=160 miles

Thus, we establish: 

160² = 170² + 200² - 2(170)(200)cos(C).

We now aim to solve for C.

25,600 = 28,900 + 40,000 - 68,000cos(C).

25,600 - 28,900 - 40,000 = -68,000cos(C).

-43,300=-68,000cos(C).

Thus, cos(C)=0.6367.

C=arc cos(0.6367)--------> C=50.45°.

Consequently, the captain should adjust toward island B by

180 - 50.45 = 129.55 degrees.

The final answer is

129.55 degrees

To start, calculate the return for each price per unit

Return = quantity sold x price per unit

Return1 = 5000 units x Php 900

Return1 = Php 4,500,000

Next, figure out the return for the other price per unit

Return2 = quantity sold x price per unit

Return2 = (5000 + 1500 units) x ( Php 900 – 100)

Return2 = Php 5,200,000

Thus, a price of Php 800 per unit will result in a higher return.
