She has 1/6 of her money left, which is $21.

2/3=4/6, so 4/6 + 1/6=5/6, which means she has 1/6 left. Divide $126 by 6 and you get $21.

Using the midpoint method, find the cross-price elasticity of demand for FedEx and UPS overnight shipping if the price of FedEx

IrinaK [193]

Answer:

Cross price elasticity using midpoint method = 0.56

Step-by-step explanation:

Using the mid-point method

Cross-price Elasticity of Demand = <u>% change in Quantity demanded of UPS</u>

% change of price of FedEx

%change in Quantity demanded of UPS

using Mid-point method = <u> Q2-Q1 </u> × 100

(Q1+Q2)÷ 2

= <u>1.3-1.2 </u> × 100

(1.2+1.3)÷2

= <u>0.1 </u> × 100

1.25

= 8%

% change in price of FedEx

using midpoint method =<u> P2-P1 </u>× 100

(P1+P2)÷ 2

=<u> 75-65 </u>× 100

(65+75)÷2

=<u> 10 </u> × 100

= 14.28%

Cross-price Elasticity of Demand = 8% ÷ 14.28%

using midpoint method = 0.56

Tony bought a $48 sweatshirt and used a coupon for a 10% discount. Keith bought an identical sweatshirt at a different store for

Westkost [7]

<h3>✽ - - - - - - - - - - - - - - - ~Hello There!~ - - - - - - - - - - - - - - - ✽</h3>

➷ final = original x multiplier

final = 48 x 0.9

final = 43.2

Tony paid $43.20

Subtract the two values:

43.2 - 42.95 = 0.25

Therefore, the correct option would be C. Keith paid $0.25 less than Tony paid

The function f is continuous son the interval [2, 10] with some of its values given in the table below. Use a right Riemann Sum

Marta_Voda [28]

The 4 subintervals are given: [2, 4], [4, 7], [7, 9], and [9, 10].

Each subinterval has length: 4 - 2 = 2, 7 - 4 = 3, 9 - 7 = 2, and 10 - 9 = 1.

Over each subinterval, we take the value of the function at the right endpoint: 3, 8, 15, and 18.

Then the integral is approximately

$\displaystyle\int_2^{10}f(x)\,\mathrm dx\approx3\cdot2+8\cdot3+15\cdot2+18\cdot1=78$

so 78.0 is the correct answer.

Eudora ran from her home to her secret laboratory at an average speed of 12\text{ km/h}12 km/h12, start text, space, k, m, slash

OleMash [197]

Answer:

Eudora spent 0.5 hours from home to library and 1.5 hours from library to school

Step-by-step explanation:

Given

Home to Library:

$S_1 = 12km/h$ -- Average Speed

Library to School

$S_2 = 76km/h$ -- Average Speed

Total

$Distance = 120km$

$Time = 2\ hr$

Required

Determine the time taken from home to library and from library to school

Let the time spent from home to library be x. So, from library to school will be: 2 - x

So, we have:

Home to Library:

$S_1 = 12km/h$ -- Average Speed

$T_1 =x$ -- Time

Library to School

$S_2 = 76km/h$ -- Average Speed

$T_2 =2 - x$ -- Time

Distance is calculated as:

$Distance = Speed * Time$

Home to Library:

$D_1 = S_1 * T_1$

$D_1 = 12 * x$

$D_1 = 12x$

Library to School:

$D_2 = S_2 * T_2$

$D_2 = 76 * (2- x)$

$D_2 = 152- 76x$

The total distance is 120km. So, we have:

$120km = D_1 + D_2$

$120 = 12x + 152 - 76x$

Collect Like Terms

$120 - 152 = 12x - 76x$

$-32 = -64x$

$-64x=-32$

Solve for x

$x = \frac{-32}{-64}$

$x = 0.5$

Recall that:

$T_1 =x$

$T_2 = 2 - x$

So, we have:

$T_1 = 0.5$

$T_2 = 2 -0.5 = 1.5$
