Visitors to a carnival can buy an unlimited-ride pass for $50 or an entrance-only pass for $20. In one day, 282 passes were sold

Ghella [55]

Answer:

Number of Unlimited passes sold were 168.

Step-by-step explanation:

Let Number of Unlimited passes sold be x

and Number of entrance-only passes sold be y.

Total number of passes sold =282

Hence,

$x+y=282 \ \ \ \ equation \ 1$

Also

Cost for unlimited-ride pass = $50

Cost for entrance-only pass = $20

Total Money for one day = $10,680

Hence,

$\$50x+\$20y=\$10,680\\$

Dividing by 10 on both side we get;

$5x+2y=1068 \ \ \ \ equation \ 2$

Now multiplying equation 1 by 2 we get;

$2x+2y=584 \ \ \ \ equation \ 3$

Now Subtracting equation 3 from equation 2 we get;

$(5x+2y=1068)-(2x+2y=584)\\3x=504\\x=\frac{504}{3}= 168$

x= 168

x+y = 282

168+y =282

y=282-168

y= 114

Hence, Number of Unlimited passes sold are 168 and Number of entrance-only pass sold is 114.

Suppose that a fashion company determines that the cost, in dollars, of producing x cellphone cases is given by C(x)equalsneg

Semenov [28]

Answer:

(a)$29.95

(b)A

Step-by-step explanation:

The cost, in dollars, of producing x cellphone cases is given by:

$C(x)=-0.05 x^2+55 x.$

We are required to evaluate: $\dfrac{C(251)-C(250)}{251-250}$

$C(251)=-0.05(251)^2+55(251)=10654.95\\C(250)=-0.05(250)^2+55(250)=10625\\\text{Therefore:}\\\\\dfrac{10654.95-10625}{251-250}=29.95$

$\dfrac{C(251)-C(250)}{251-250}=\$29.95$

The value calculated above represents the additional cost to produce one more item after making 250 items.
