How do you find the cost of one pizza if one pizza cost three times as much as a soda and the price of one pizza and one soda is $5?
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)
