Help fast please !! Ryan is going to an amusement park. The price of admission into the park is $25, and once he is inside the park, he will have to pay $3 for every ride he rides on. How much money would Ryan have to pay in total if he goes on 7 rides? How much would he have to pay if he goes on r rides?

1. $46

2. C= 25+ 3r

Step-by-step explanation:

In this problem, we are going to model an equation for the cost of Ryans rides in the park

the $25 is a constant fee

while the $3 is a fee that depends on the number of rides

let the cost be C

and let the number of rides be r

How much would he have to pay if he goes on r rides?

C= 25+ 3r

How much money would Ryan have to pay in total if he goes on 7 rides?

C= 25+3(7)

C= 25+21

C= $46

step-by-step explanation:

answer: the price of one pound cabbage = $ 0.8

the point (10,8) represents that the cost of 10 pounds cabbage is $ 8

step-by-step explanation:

since, here is a proportional relation between the number of pounds of cabbage (x) and the price in dollars (y).

therefore, we can write,

⇒ y = k x

where k is the constant of proportionality.

now, point (5,4) is in the line.

thus, it will satisfies the above equation of line.

⇒ 4 = 5 k

⇒ k = 0.8

thus, the equation of the line is,

y = 0.8 x

a) for x = 1,

y = 0.8

therefore, the cost of one pound of cabbage is 0.8 dollars.

b) in the below graph (10,8) represents that the cost of 10 pounds of cabbage is 8 dollars.
