A manufacturer has been selling hats at $8 a piece, and at this price, consumers have been buying 6000 hats per month. The manuf
gtnhenbr [62]

Answer:

$10

Step-by-step explanation:

Initial selling price per hat= $8

Number of hat sold= 6000

Revenue generated = $8*6000=$48000

Cost of producing hats = $4 per hat

Production cost = $4*6000=$24000

Profit = $48000-$24000=$24000

Increasing the price per hat by $2

Selling price per hat = $2+$8=$10

Number of hats sold are 500 fewer = 6000-500= 5500 hats

Revenue generated = $10*5500 = $55000

Cost of production is the same , where $4 per hat = $4*5500 =$22000

Profit generated = $55000-$22000 =$33000

This means at a price of $10 per hat , selling 500 fewer hats, the manufacture still makes a profit of $33000 which is $9000 more. It will be reasonable to hat at $10 because the profit will increase.

stich3 [128]

Answer:

Carl has to sell at least 8 cookies.

c\geq 7.5

Step-by-step explanation:

Carl gets \$1.50 by selling 1 chocolate bar.

Earning from chocolate bars:

Total\ chocolate\ bar=20\\\\Earning\ from\ one\ chocolate\ bar=\$1.50\\\\Total\ earning\ from\ chocolate\ bar=Total\ chocolate\ bar\times cost\ of\ 1\ chocolate\ bar=20\times 1.5=\$30

Earning From cookies:

Let\ total\ number\ of\ cookies=c\\\\Cost\ of\ 1\ cookie=\$2\\\\Earning\ from\ cookies=2\times c=2c

Total\ earning=Earning\ from\ cookies+Earning\ from\ cookies+Earning\ from\ chocolate\ bars\\\\Total\ earning=30+2c

Carl wants to raise at least \$55

Total\ earning\geq 55\\\\2c+30\geq 55\\\\2c\geq 55-30\\\\2c\geq 15\\\\c\geq7.5

The value of the figure's surface area is equal to the value of the figure's volume find the value of x. the picture is of recta
emmasim [6.3K]
Surface are of a rectangular prism = 2(l x w + l x h + w x h) = 2(10 x 3 + 10x + 3x) = 2(30 + 13x) = 60 + 26x

Volume of a rectangular prism = l x w x h = 10 * 3 * x = 30x

Since surface area = volume
60 + 26x = 30x
4x = 60
x = 15 in
