We can begin by translating the word problem into a mathematical statement.

Cost of Soda + Cost of Pizza = Total Cost

If we make the cost of the soda equal to n.
Then the cost of the pizza is 3 times n.

Soda = n
Pizza = 3n
Total Cost = n + 3n

n + 3n = $5

4n = $5 (combine like terms)

$n = ($5)/4$ (divide by 4 to isolate the variable)

$n = $1.25$
