Answer:

$4\frac{5}{8}\div \:\:2\frac{3}{4}=\frac{37}{22}$

Step-by-step explanation:

Given

$4\frac{5}{8}\div \:2\frac{3}{4}$

$\mathrm{Convert\:mixed\:numbers\:to\:improper\:fractions}:\quad 4\frac{5}{8}=\frac{37}{8}$

$=\frac{37}{8}\div \:2\frac{3}{4}$

$\mathrm{Convert\:mixed\:numbers\:to\:improper\:fractions}:\quad 2\frac{3}{4}=\frac{11}{4}$

$=\frac{37}{8}\div \frac{11}{4}$

$\mathrm{Apply\:the\:fraction\:rule}:\quad \frac{a}{b}\div \frac{c}{d}=\frac{a}{b}\times \frac{d}{c}$

$=\frac{37}{8}\times \frac{4}{11}$

$\mathrm{Cross-cancel\:common\:factor:}\:4$

$=\frac{37}{2}\times \frac{1}{11}$

$\mathrm{Multiply\:fractions}:\quad \frac{a}{b}\times \frac{c}{d}=\frac{a\:\times \:c}{b\:\times \:d}$

$=\frac{37\times \:1}{2\times \:11}$

$\mathrm{Multiply\:the\:numbers:}\:37\times \:1=37$

$=\frac{37}{2\times \:11}$

$\mathrm{Multiply\:the\:numbers:}\:2\times \:11=22$

$=\frac{37}{22}$

Therefore,

$4\frac{5}{8}\div \:\:2\frac{3}{4}=\frac{37}{22}$

Sam owns a chain of fast food restaurants that operated 200 stores in 1999. If the rate of increase is 8% annually, how many sto

yawa3891 [41]

Answer:

370 stores

Step-by-step explanation:

Given data

initial number of stores P= 200

r= 8%

t= 1999-2007= 8 years

Let us apply the compound interest expression to find the final amount of stores

A= P(1+r)^t

A= 200(1+0.08)^8

A= 200(1.08)^8

A= 200*1.85

A=370

Hence the number of stores in 2007 is 370 stores
