<u>Complete Question:</u>

<em>Hannah was shopping for a summer dress at a store near her home. On the rack where she found the dress she wanted, she saw two signs. The first one read, “Clearance: 15% off.” The second one read, “$10 off—Instant Savings.” The original price of the dress was $65.00. Hannah lives in Oregon, where there is no sales tax. </em>

  • <em> How much will Hannah pay for the dress if the 15% discount is applied before the $10 discount? </em>
  • <em> How much will Hannah pay for the dress if the $10 discount is applied before the 15% discount?</em>

<em />

<u>First Part:</u>

First, 15% off, then $10 off. So

65 - (0.15)(65) = $55.25

Now $10 off makes it:

55.25 - 10 = $45.25

Hannah will pay $45.25

<u>Second Part:</u>

Now, first we have to apply $10 discount, so:

65 - 10 = $55

Now, we apply 15% discount, thus:

55 - (0.15)(55) = $46.75

Hannah will pay $46.75

A system of equations is shown below. y = –x – 3 5x + 2y = 9 What is the solution to this system?
erastovalidia [21]

Answer:

x=5\ and\ y=-8

The solution of the system can be given as (5,-8).

Step-by-step explanation:

Given system of equations:

y=-x-3

5x+2y=9

To solve the given system of equations:

Solution:

We will use substitution to solve the given system.

We will substitute the y values in terms of x from the equation y=-x-3 into the other equation to solve for x

Substituting y=-x-3 into 5x+2y=9.

We have:

5x+2(-x-3)=9

<em>Using distribution.</em>

5x-2x-6=9

<em>Combining like terms.</em>

3x-6=9

Adding 6 both sides.

3x-6+6=9+6

3x=15

Dividing both sides by 3.

\frac{3x}{3}=\frac{15}{3}

∴ x=5

<em>Plugging in x=5 into y=-x-3.</em>

We have,

y=-5-3

∴ y=-8

The solution of the system can be given as (5,-8).

A cruise left port A and traveled towards port B 225 km away. After 1.5 hours of travel, the cruise was stopped for a half an ho
Softa [21]

Answer:

50

Step-by-step explanation:

v = the original speed of the cruise

d = 225 km the distance passed

t = d/v = 225/v the total time of the travel

v*1.5 + (v + 10)(d/v - 1.5 - 0.5) = d (using the formula distance = speed*time)

1.5v + (v + 10)(225/v - 2) = 225

Marina86 [1]
f(t) =  -16t^{2} +48t + 100
Average rate of change from t = 3 seconds to t = 5 seconds = \frac{f(5)-f(3)}{5-3} =  \frac{(-16( 5^{2})+48(5)+100)-(-16( 3^{2})+48(3)+100  }{2}=\frac{(-16(25)+240+100)-(-16(9)+144+100)}{2} = \frac{(-400+240+100)-(-144+144+100)}{2}= \frac{-60-100}{2} = \frac{-160}{2} = -80
