1 over 3b = 4 over 5 . Which of the following equals b in this equation? (4 points)
vfiekz [6]

Answer:

none of the answers listed are equivalent to b (22/5, 11/8, 2/5, 1/4)

Step-by-step explanation:

\frac{1}{3b} = \frac{4}{5}

to simplify, cross multiply

(1 · 5  =  3b · 4)

(5 = 12b)

divide both sides by 12 to isolate b,

\frac{5}{12} =\frac{12b}{12}

\frac{5}{12} = b

None of the answers listed are equivalent to 5/12

\frac{5}{12} \neq\frac{22}{5}

\frac{5}{12} \neq\frac{11}{8}

\frac{5}{12} \neq\frac{2}{5}

\frac{5}{12} \neq\frac{1}{4}

A store manager predicts that 150 blankets will be sold if each blanket
Sever21 [200]

Answer:

$47

Step-by-step explanation:

Given: Store manager have predicted that 150 blanket can be sold at $32 each.

Also he has predicted sales of 2 blanket will decrease with $1 increase in price.

Now, finding price at which 120 blanket can be sold.

As we know cost of 150 blanket is $32 and we are finding for 120 blanket, which mean we have to increase price to decrease sales.

∴ 150-120 = 30\ blankets

Using unitary method to find correct price.

For 2 decrease in sales = $1 increase in price                

∴ 30 decrease in sales of blanket = $15 increase in price

Next, price of 120 blanket = Price of 150\ blanket + increase\ in\ price

Price\ of\ 120\ blanket = 32+15 = \$ 47

∴ $47 should be the price for at least 120 blanket to be sold.
