Matt invested $1500 into a stock of his choice. After two years, he had received
EleoNora [17]

For this question, the time given confuses me.  I know the rate of return is just total return divided by divided by investment, Assuming that Matt received the $400 in dividends as cash payouts, and they weren't reinvested into buying shares of the stock, then his total return over two years was $500, Now, if Matt's dividends were reinvested into the stock - and if you have a 401(k) or IRA, that's what usually happens - then his ROI would have been only 6% because he only made a profit of $100 on an investment of $1500. Note:  In the real world, in current market conditions, Matt probably would have got about a 5% return on a good stock, and Bella would have received about 0.05% on a savings account.

hope this helped you ;)

Scott delivers 14 newspapers in 10min. This is 28% of his round. A) How many more papers does Scott need to deliver? b) Scott co
Leya [2.2K]

Answer:

A)36

B)50 minutes 40 second

Step-by-step explanation:

<h3>Question-A:</h3>

according to the question

\begin{array}{ccc}28\%  \:  \: \text{newspaper} \implies 14  \\ 100\%  \:  \: \text{newspaper} \implies  \displaystyle  \frac{14 }{28\%}\\ \rm since \: \% =  \dfrac{1}{100}   \: we \: get : \\  \\  \displaystyle \xrightarrow{ } \frac{14}{ \dfrac{28}{100} }  \\   \\ \xrightarrow{ \rm \: simplify \:  complex \:  fraction} \displaystyle \: 14 \times  \frac{100}{28} \\  \xrightarrow{simplify} 50 \end{array}

since he had already delivered 14 newspaper he needs to deliver

\displaystyle 50 - 14

simplify Substraction:

\displaystyle36

<h3>Question-B:</h3>

remember that,

\displaystyle  \text{rate} =  \frac{ \rm \: amount}{ \rm time}

given that,

  • amount:14
  • time:10

thus substitute:

\displaystyle  \text{rate} =  \frac{ \rm 7}{ \rm5}

so,

\displaystyle \frac{ \rm 7}{ \rm5}  \times 36

simplify:

\displaystyle 50.4

hence,

It will take 50 minutes 40 second to deliver all of them
