The Perez family is researching the cost of keeping their dog at a kennel during an upcoming vacation. The local kennel allows “Silver” families to pay a rate of $36 per day. For a fee, families can buy a “Gold” membership and will be allowed to board their dogs at a discounted rate as shown in the table.Total Cost, Including Membership Fee, to Board a DogType of membership1 Day2 Days7 DaysSilver$36$72$252Gold$70$90$190What is the cost of a Gold membership?
The Gold total increases from $70 for 1 day to $90 for 2 days, so the discounted boarding rate is $20 per day. Subtract that one-day boarding cost from the $70 total: $70 − $20 = $50. The Gold membership costs $50.
