Andrea has a savings account with $80 that earns 2% interest per

lianna [129]

Answer:

After 10 years, she will has $96 in her bank.

Step-by-step explanation:

It is given that Andrea's saving account is $80 and earns 2% interest per year as a Simple Interest (Not Compounded). Using simple interest formula, Interest = (P×R×T)/100 where P is the principal, R is the interest rate and T is number of years :

$I = \frac{p \times r \times t}{100}$

P = $80

R = 2%

T = 10 years

$I = \frac{80 \times 2 \times 10}{100}$

$I = \frac{1600}{100}$

$I = 16$

It is given that the interest amount is $16. So the total amount she has after 10 years in the bank is $96 :

interest amount = $16

principal = $80

total = $16 + $80

= $96

A recipe for brownies calls for 2.5 cups of flour. The recipe makes 10 servings. How many cups of flour are needed to make 13 se

quester [9]

It would be 3.25 cups

Since there is 2.5 cups for 10 servings then 0.25 per serving multiply that by 13 servings and you get 3.25.So it would be 3.25 cups for 13 servings

Revenue from Monorail Service, Las Vegas In 2005 the Las Vegas monorail charged $3 per ride and had an average ridership of abou

Karolina [17]

Answer:

A)The required linear demand equation ( q ) = -4500p + 41500

B) $4.61

$95680.55

C) No it would not have been possible by charging a suitable price

Step-by-step explanation:

A) find the linear demand equation

given two points ; ( 3, 28000 ) and ( 5, 19000 )

slope ( m ) = ( y2 - y1 ) / ( x2 - x1 )

= ( 19000 - 28000 ) / ( 5 - 3 ) = -4500

slope intercept is represented as ; y = mx + b

where y( 28000) = -4500(3) + b

hence b = 41500

hence ; y = -4500x + 41500

The required linear demand equation ( q ) = -4500p + 41500 ----- ( 1 )

p = price per ride

B ) Determine the price the company should charge to maximize revenue from ridership and corresponding daily revenue

Total revenue ( R ) = qp

= p ( -4500p + 41500 )

hence R = -4500p^2 + 41500p ------ ( 2 )

To determine the price that should maximize revenue from ridership we will equate R = -4500p^2 + 41500p to a quadratic equation R(p) = ap^2 + bp + c

where a = -4500 , b = 41500 , c = 0

hence p = $-\frac{b}{2a}$ = $- \frac{41500}{2(-4500)}$ = 4.61

$4.61 is the price the company should charge to maximize revenue from ridership

corresponding daily revenue = R = -4500p^2 + 41500 p

where p = $4.61

hence R = -4500(4.61 )^2 + 41500(4.61) = $95680.55

C) No it would not have been possible by charging a suitable price
