C+a=9

c=9-a

....

210c+315a=2205, using c found above in this gives you:

210(9-a)+315a=2205

1890-210a+315a=2205

1890+105a=2205

105a=315

a=3, and since c=9-a

c=6

So 6 children and 3 adults went on the trip to Hawaii.

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.
