You and a friend are heading to Frankie's Fun Park (Columbia, SC). You have $100 for the day, and plan to spend your time riding

Rufina [12.5K]

Answer:

$8r + 6s = 100$ --- (a)

$s = -2$ ---- (b)

Step-by-step explanation:

Given

Per ride (r) = $8

Per baseballs (s) = $6

Total = $100

Required

Represent using an equation

If 1 ride is $8.

r rides would be 8r

If 1 baseball is $6

s baseballs would be 6r.

So, total is:

$8r + 6s = 100$

Solving (b):

Value of s when r = 14

$8r + 6s = 100$

Substitute 14 for r

$8 * 14 + 6s = 100$

$112+ 6s = 100$

Solve for 6s

$6s = 100 - 112$

$6s = -12$

Solve for s

$s = -12/6$

$s = -2$

The yearly cost y for driving a certain car is $7,800 for 10,000 miles

Licemer1 [7]

Answer:

y = 0.36x + 4200.00

15100.00 miles.

Step-by-step explanation:

If the yearly cost for driving x miles is given by y dollars then the two ordered pairs to find the linear relation between x and y are (10000,7800) and (20000,11400).

So, the equation will be

$\frac{y - 11400}{11400 - 7800} = \frac{x - 20000}{20000 - 10000}$

⇒ $\frac{y - 11400}{3600} = \frac{x - 20000}{10000}$

⇒ $y - 11400 = \frac{9}{25}(x - 20000)$

⇒ $y - 11400 = \frac{9}{25}x - 7200$

⇒ $y = \frac{9}{25}x + 4200$

⇒ y = 0.36x + 4200.00 ........... (1) (Answer)

Now, for y = $9636.00, from equation (1),

9636 = 0.36x + 4200

⇒ 0.36x = 5436

⇒ x = 15100.00 miles. (Answer)

Mashcka [7]

$1.10 per pound for the 1-pound bag.
$0.96 per pound for the 2-pound bag.
$0.92 per pound for the 3-pound bag.

As the quantity of sugar increases, the unit cost decreases.
