SA= 49.5 (m but it says no units)

Explanation: find the area of one of the triangles, A=(b*h)/2, and then one of the rectangles, A=l*w. Multiply the triangles area by two, there are two triangles. Multiply the rectangles areas by three, there are three rectangles. I’ve included calculations in the picture below.

A movie-theater employee notes an inverse relationship between the theater's popcorn sales and its nacho sales. On a given night

zubka84 [21]

the employee earned $1813 from Nachos

Explanation:

The theater's popcorn sales is inversely proportional to nacho sales

Let theater's popcorn = P

nacho sales = N

$P\text{ }\alpha\text{ }\frac{1}{N}$

Equating the relationship:

$\begin{gathered} P\text{ = k(}\frac{1}{N}) \\ P\text{ = }\frac{k}{N} \\ \text{where k = constant of proportionality} \end{gathered}$

when theater sales = $2,254

Nacho sales = $1,628

$\begin{gathered} 2254\text{ =}\frac{k}{1628} \\ k\text{ = 2254(1628)} \\ k\text{ = 3}669512 \end{gathered}$

The relationship becomes:

$P\text{ = }\frac{3669512}{N}$

When cost of the theater popcorn = $2,024

The cost from nachos = ?

We would use the relationship to get the above:

$\begin{gathered} 2024\text{ = }\frac{3669512}{N} \\ 2024N\text{ = 3669512}18 \\ N\text{ = }\frac{\text{3669512}}{2024} \\ N\text{ = }1813 \end{gathered}$

Hence, the employee earned $1813 from Nachos
