Answer

The range of possible prices is \$51.00-\$107.10.

Work Step by Step

The cheapest possible tent during the sale would be 25% off the tent with the lowest regular price, \$68. If the price is reduced by 25%, the price you pay is 75%. The most expensive possible tent during the sale would be 10% off the tent with the highest regular price, \$119. If the price is reduced by 10%, the price you pay is 90%. Let t be the sale price of a tent. $68\times0.75\leq t\leq 119\times0.90$ $51\leq t\leq 107.10$
