A stock was priced at $12 3/8 per share. It rose in price by $3 1/4 per share. What was its new price?
lubasha [3.4K]

Option A

The new price is $ 15 \frac{5}{8}

<h3><u>Solution:</u></h3>

Given that, a stock was priced at $ 12 \frac{3}{8} per share.

It rose in price by $ 3 \frac{1}{4} per share.

New price = old price + rise in price

Thus to find out the new price, we have to add old price and rise in price

\text { So, new price }=\$ 12 \frac{3}{8}+\$ 3 \frac{1}{4}

\text { New price }=\frac{12 \times 8+3}{8}+\frac{3 \times 4+1}{4}

On solving we get,

\text { New price }=\frac{96+3}{8}+\frac{12+1}{4}

\begin{array}{l}{\text { New price }=\frac{99}{8}+\frac{13}{4}=\frac{99+26}{8}} \\\\ {\text { New price }=\frac{125}{8}}\end{array}

On converting to mixed fraction,

\begin{array}{l}{\text { New price }=\frac{120+5}{8}} \\\\ {\text { New price }=15 \frac{5}{8}}\end{array}

Hence, the new price is 15 \frac{5}{8}, so option A is correct.

The amount of red blood cells in a blood sample is equal to the total amount in the sample minus the amount of plasma. What is t
zaharov [31]

Answer:

Step-by-step explanation:

The question is:

The amount of red blood cells in a blood sample is equal to the total amount in the sample minus the amount of plasma. What is the total amount of blood drawn? Red blood cells = 45% Plasma = 5.5 ml

Solution:

We have given:

The amount of red blood cells in a blood sample is equal to the total amount in the sample minus the amount of plasma. We need to find how many ml is 1% of blood.

The equation we get is:

Red blood cells = total sample - amount of plasma

45% = 100% - 5.5 ml

Combine the percentages:

5.5 ml = 100%-45%

5.5 ml = 55%

0.1 ml = 1%

1% = 0.1 ml

Now you can find out red blood cells volume or total sample volume.

Red blood cells volume = 45% x 0.1ml/%

= 4.5ml

Total sample volume =100% x 0.1ml/%

= 10ml .
