Answer:
The cost of r rides = 2r + 10
The cost of 15 rides = $40
Step-by-step explanation:
The form of the linear equation is y = m x + b, where
Assume that the cost of r rides is c
∵ The number of the ride is r
∴ x = r
∵ The cost of r rides is c
∴ y = c
∵ The price of admission into the park is $10 ⇒ initial amount
∴ b = 10
∵ She will have to pay $2 for every ride ⇒ rate of change
∴ m = 2
→ Substitute them in the form of the equation above
∴ c = 2r + 10
∴ The cost of r rides = 2r + 10
∵ She goes on 15 rides
∴ r = 15
→ Substitute it in the form of the equation
∵ c = 2(15) + 10
∴ c = 30 + 10
∴ c = 40
∴ The cost of 15 rides = $40

Answer:
1) k = 3
2) 3, 4, 5
3) k + (k + 2) + (k + 4) = 4k
4) 6, 8, 10
Step-by-step explanation:
Jared used the equation;
k + (k + 1) + (k + 2) = 4k
Let's find k.
3k + 3 = 4k
4k - 3k = 3
k = 3
Thus,the integers will be;
3, (3 + 1) and (3 + 2)
This is; 3, 4, 5
He is looking for consecutive even integers but yet got 3 and 5 which are odd numbers. However, he should have used the format;
k, (k + 2), (k + 4) as the 3 consecutive even integers.
Thus, rewriting the main equation gives;
k + k + 2 + k + 4 = 4k
3k + 6 = 4k
4k - 3k = 6
k = 6
Thus,the integers are;
6, (6 + 2), (6 + 4)
This is; 6, 8, 10
8.2 to the nearest one is 8
