The sale price of a spring break vacation package was $209.99 the travel agent said by booking early you saved $20.00. Find the
prisoha [69]

Answer:

<em></em>\%\ decrease =  9.52\%<em></em>

<em></em>

Step-by-step explanation:

Given

Sales\ Price = \$209.99

Saved = \$20.00

Required

Determine the %decrease

First, we need to determine the amount paid

Amount = Sales\ Price - Amount\ Saved

Amount = \$209.99 - \$20.00

Amount = \$189.99

The percentage decrease is the calculated as follows:

\%\ decrease = -100\% * \frac{Final - Initial}{Initial}

In this case;

Initial = Sales\ Price = \$209.99

Final = Amount\ Paid = \$189.99

So; we have:

\%\ decrease = -100\% * \frac{189.99 - 209.99}{209.99}

\%\ decrease = -100\% * \frac{-20}{209.99}

\%\ decrease = 100\% * \frac{20}{209.99}

\%\ decrease =  \frac{2000\%}{209.99}

\%\ decrease =  9.52426306015\%

<em></em>\%\ decrease =  9.52\%<em> (Approximated)</em>

Through (-3, 2) parallel to y = -2x-1
Slav-nsk [51]

Answer:

y = - 2x - 4

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = - 2x - 1 ← is in slope- intercept form

with slope m = - 2

Parallel lines have equal slopes , then

y = - 2x + c ← is the partial equation

To find c substitute (- 3, 2 ) into the partial equation

2 = 6 + c ⇒ c = 2 - 6 = - 4

y = - 2x - 4 ← equation of parallel line

John and his son are building a boxcar for a group competition. According to the rules of the competition, the length of the car
kozerog [31]

Answer:

x ≥ y + 2

0.50 (x) (x+3) + 2.25 (4) (y) ≤ 50

Step-by-step explanation:

x = width of the car

x+3 = length of the car

y = radius of the car

The width must be at least 2 inches greater than the radius, so:

x ≥ y + 2

The total cost must be no more than $50, so:

0.50 (x) (x+3) + 2.25 (4) (y) ≤ 50
