Each issue of a magazine costs $6.95 at the supermarket. A 6-month digital subscription costs $30.99. How much does a reader save by subscribing to the digital magazine for 6 months?
The 6-month cost of buying individual issues at the supermarket would be 6*6.95=$<<6*6.95=41.70>>41.70
Thus, by buying the digital subscription, a reader would save 41.70-30.99=$<<41.70-30.99=10.71>>10.71. Answer: \boxed{10.71}.
To calculate the savings of subscribing to the digital magazine for 6 months, we need to determine the cost of purchasing the magazine individually for 6 months and then subtract the cost of the digital subscription.
The cost of purchasing the magazine individually for 6 months can be calculated by multiplying the price per issue by the number of months:
Cost of purchasing magazines individually for 6 months = 6.95 * 6
Next, we subtract the cost of the digital subscription from the cost of purchasing the magazines individually for 6 months:
Savings = (Cost of purchasing magazines individually for 6 months) - (Cost of digital subscription for 6 months)
