Question

Kasey subscribes to a running magazine that costs a monthly fee of $10 and $5 per additional magazine. Which of the following expressions gives Kasey’s cost, in dollars, for y months during which she ordered x additional magazines?

Answer 1

Kasey's cost for y months and x additional magazines can be expressed as: 10y + 5x.

This expression takes into account the monthly fee of $10 and the cost of each additional magazine of $5. The number of months (y) is multiplied by the monthly fee to calculate the cost for that time period, and the number of additional magazines (x) is multiplied by their cost to find the total additional cost
