Question

the cost of a telephone call 75 cents plus 25 cents times the number of minutes. write an algebraic expression that models the cost of a telephone call the last t minutes

Answer 1

Since the cost of the telephone cost is 25 cents per minute, and by using the variable you provided, "t", the equation thus far is 25t=cost, or 25 multiplied by "t".

Since the telephone also charges 75 cents at the start, we just have to add it into our equation, making 75+25t=cost of telephone call in cents.

answer: 75+25t=cost of telephone call in cents
