love history [14]

Answer:

C = 299x + 59.99y + 29.99z

Step-by-step explanation:

An algebraic expression is an expression in which it involves the numbers like 1,2,3 also it includes the operations such as additions, subtraction, multiplication, etc

Fo mentioning an algebraic expression, we do have following components

x = number of consoles purchased

y = number of games purchased

z = number of controllers purchased

C = total cost

Also, the total cost would be equivalent to the sum of the price and then it multiplied with the numbers as stated above

So, the algebraic expression is

C = 299x + 59.99y + 29.99z
