Each game costs 1$ and each ride costs $3.50. sam spent $28.50 altogether at the carnival and the number of rides she went on is 3 more than the number of games she played. determine the number of games sam played and the number of rides sam went on.

Sam played 5 games and went on 8 rides

Step-by-step explanation:

Let r represent the number of rides that Sam went on.

Let g represent the number of games that Sam played

the number of rides she went on is 3 more than the number of games she played. This means that

r = 3 + g

Each game costs 1$ and each ride costs $3.50. Sam spent $28.50 altogether at the carnival. This means that

3.5r + g = 28.50 - - - - - - -1

Substituting r = 3 + g into equation 1, it becomes

3.5(3+g) + g = 28.50

10.5 + 3.5g + g = 28.50

4.5g = 28.5 - 10.5

4.5g = 18

g = 18/4.5

g = 5

r = 3 + g = 3 + 5

r = 8

19.63 inches

Step-by-step explanation:

The area of a circle is found by using the formula

A = πr²

r is the radius of the circle, which is the diameter divided by two.

D = 5 in so r = D ÷2

5 ÷ 2 = 2.5 inches for the radius.

A = π (2.5)²

A = π (6.25)

A = (3.14)(6.25)

A = 19.625 inches
