Answer:

The original selling price would be $ 515.87 ( approx )

Step-by-step explanation:

Consider the complete question is :

"A sporting goods store manager was selling a ski set for a certain price. The manager offered the markdowns​ shown, making the​ one-day sale price of the ski set ​$325. Find the original selling price of the ski set. It was marked down 10% and 30%"

Suppose x be the original selling price ( in dollars ),

After marking down 10%,

New selling price = x - 10% of x = x - 0.1x = 0.9x

Again after marking down 30%,

Final selling price = 0.9x - 30% of 0.9x

= 0.9x - 0.3 × 0.9x

= 0.9x - 0.27x

= 0.63x

According to the question,

0.63x = 325

\implies x =\frac{325}{0.63}=\$ 515.87

Therefore, the original selling price would be $ 515.87.

PLEASE HELP!!
vesna_86 [32]

Answer:

k=-3

x=63

Step-by-step explanation:

The equation for direct variation is

y = kx  where k is the constant of variation

We know x and y we can solve for k

-87 = k*29

Divide each side by 29

-87/29 = k

-3 =k

y= -3x

Now we know y = -189, we can find x

-189 = -3x

Divide by -3

-189/-3 = -3x/-3

63 =x

Lin opened a lemonade stand during the summer. She
AnnyKZ [126]

Answer:

59 cups ;

10 cups

Step-by-step explanation:

Given that he fitted model :

c = 2t - 89

Where, c = cups of lemonade sold ; t = high temperature

On a day when high temperature is 74 degrees ; cups of lemonade sold

Hence,

c = 2t - 89

c = 2(74) - 89

c = 148 - 89

c = 59 cups

Sunday is expected to be 5 degree warmer than on Saturday :

The number of cups sold on Sunday using the fitted model should be :

Difference in temperature between Saturday and Sunday multiplied by the slope value

Slope value from the model = 2

Temperature difference = 5

Difference in Number of cups :

2 * 5 = 10 cups

Number of lemonade sold on Sunday will be 10 cups more than that sold on Saturday
