\text {Hello! Let's Solve this Equation!}

\text {The First Step is to Multiply 3 in the Parentheses:}

\text {3*x=3x}\\\text {3*8=24}

\text {Your new Problem is: 3x-24=29.7}

\text {The Next Step is to Add 24:}

\text {3x-24+24=29.7+24}\\\text {=53.7}

\text {Your new Problem is: 3x=53.7}

\text {The Final Step is to Divide 3:}

\text {3x/3=53.7/3}

\text {Your Answer would be:}

\fbox {x=17.9}

\text {Best of Luck!}

DaniilM [7]

Answer: 19 years

Step-by-step explanation:

Given

Amount invested \$400

Rate of interest R=6\%

after 1-year amount becomes

A=400\left (1+6\%\right)\\A=400\left (1+0.06\right)\\A=400\times 1.06\\A=\$424

After n years it is

A=400\left (1.06\right)^n

Sum accumulated is \$1200

\Rightarrow 1200=400\left(1.06\right)^n\\\Rightarrow 3=\left(1.06\right)^n\\\text{Taking log both sides}\\\Rightarrow n=\dfrac{\ln 3}{\ln 1.06}\\\\\Rightarrow n=18.85\approx 19\ \text{years}

Calculate the trade discount for 3030 boxes of computer paper if the unit price is ​$14.9314.93 and a single trade discount rate
zhannawk [14.2K]

Answer:

Total trade discount on 30 boxes = $201.555

Step-by-step explanation:

1 box = $14.93

And a trade discount of 45% is allowed on a single box,

Therefore, the discount on one $14.93 box will be

45% × $14.93 = $6.7185

So, if there are now 30 boxes, the trade discount on all 30 boxes will be

30 × (trade discount on one box) = 30 × ($6.7185) = $201.555

Hope this helps!
