Answer:
The ratio of the Living Longer subscription cost to the Bouncing Babies subscription cost can be found by dividing the cost of Living Longer by the cost of Bouncing Babies:
$39.95 ÷ $49.95 ≈ 0.80
Rounded to two decimal places, the ratio of the Living Longer subscription cost to the Bouncing Babies subscription cost is approximately 0.80. Therefore, for every dollar spent on a subscription to Bouncing Babies magazine, one would need to spend approximately $0.80 on a subscription to Living Longer magazines.
