Answer:

<h3>Hi, to answer this question we have to write a proportion.</h3><h3>Proportion = square feet/ cost</h3><h3>Since a 1425 square feet shop cost 45600 to lease, the proportion is equal to: 1425/45600</h3><h3>For a 1820 square feet shop: 1820/x</h3><h3>Where x is the cost per year for leasing a 1820 square feet shop</h3><h3>1425ft/\$456000=1820ft/\$x</h3><h3>1425/456000 = 1820 / x</h3><h3>Solving for x:</h3><h3>x = 1820/(1425/456000)</h3><h3>x=\$582,400</h3>

Answer:

$\large \boxed{\text{3.0 mi/h}}$

Step-by-step explanation:

Let x = the current of the river

Then 21 + x = the speed going downstream (with the current)

a nd 21 - x = the speed going upstream (against the current)

Distance = speed × time

d = st

t = d/s

Time going downstream = time going upstream

$\begin{array}{rcll}\dfrac{2.4}{21+ x}& = & \dfrac{1.8}{21 - x} &\\\\2.4& = &(21 + x) \dfrac{1.8}{21 - x} &\text{Multiplied each side by (21 + x)}\\\\2.4(21 - x)& = & 1.8(21 + x) &\text{Multiplied each side by (21 - x)}\\50.4 - 2.4x&=& 37.8 + 1.8x&\text{Removed parentheses}\\50.4 & = & 37.8 + 4.2x & \text{Added 2.4x to each side}\\\end{array}\\$

$\begin{array}{rcll}12.6 & = & 4.2x & \text{Subtracted 37.8 from each side}\\x & = &\dfrac{12.6}{4.2}&\text{Divided each side by 4.2}\\\\ & = &\mathbf{3.0}& \text{Simplified}\\\\\end{array}\\\text{The current is $\large \boxed{\textbf{3.0 mi/h}}$}$
