Answer:

72

Step-by-step explanation:

<u>Cost of each item:</u>

Pizza = $1.50, Hotdogs = $1.25

<u>Number of each item:</u>

Pizza = x, Hotdogs = x + 20

<u>Total cost:</u>

1.25x + 1.5(x + 20) = 173
1.25x + 1.5x + 30 = 173
2.75x = 143
x = 143/2.75
x = 52

<u>Number of slices of pizza:</u>

52 + 20 = 72

Step-by-step explanation:

$\mathrm{Write\:the\:numbers\:one\:under\:the\:other,\:line\:up\:the\:decimal\:points.}$

$\mathrm{Add\:trailing\:zeroes\:so\:the\:numbers\:have\:the\:same\:length.}$

$\begin{matrix}\:\:&5&.&3&1&6\\ -&1&.&9&4&2\end{matrix}$

$\mathrm{Subtract\:each\:column\:of\:digits,\:starting\:from\:the\:right\:and\:working\:left}$

$\mathrm{In\:the\:bolded\:column,\:subtract\:the\:second\:digit\:from\:the\:first}:\quad \:6-2=4\\$

$\frac{\begin{matrix}\:\:&5&.&3&1&\textbf{6}\\ -&1&.&9&4&\textbf{2}\end{matrix}}{\begin{matrix}\:\:&\:\:&\:\:&\:\:&\:\:&\textbf{4}\end{matrix}}$
