A furniture store pays a wholesale price for a mattress. Then, the store marks up the retail price to 150% of the wholesale pric
slega [8]
Part A:

Given that <span>the mattress is sold for 50% off of the retail price, let the retail price of the mattress be x, then

50% of x = 1200
⇒ 0.5x = 1200
⇒ x = 1200 / 0.5 = 2400

Therefore, </span><span>the retail price of the mattress, before the discount is $2,400.



Part B:

Given that </span><span>the store marks up the retail price to 150% of the wholesale price. Let the whole sale price be p, then

(100% + 150%) of p = 2400
250% of p = 2400
2.5p = 2400
p = 2400 / 2.5 = 960.

Therefore, </span><span>the wholesale price, before the markup was $960</span>

The basketball boosters are selling school t-shirts for $20 and warm up pants for $45. Last week they sold 100 items and collect
lesya [120]

They sold 76 t-shirts and 24 warm up pants.

Step-by-step explanation:

Cost of one t-shirt = $20

Cost of warm up pants = $45

Total sold = 100

Worth of sold items = $2600

Let,

x be the number of t-shirts.

y be the number of warm up pants.

According to statement;

x+y=100    Eqn 1

20x+45y=2600   Eqn 2

Multiplying Eqn 1 by 20

20(x+y=100)\\20x+20y=2000\ \ \ Eqn\ 3

Subtracting Eqn 3 from Eqn 2

(20x+45y)-(20x+20y)=2600-2000\\20x+45y-20x-20y=600\\25y=600\\

Dividing both sides by 25

\frac{25y}{25}=\frac{600}{25}\\y=24\\

Putting y=24 in Eqn 1

x+24=100\\x=100-24\\x=76

They sold 76 t-shirts and 24 warm up pants.
