lin has a lemonade stand. c stands for the cups she sells and t stands for the temperature. a computer company found the best equation for the line for the data is c=2t-89. on sunday the weather is 6 degrees warmer then saturday. how many cups does she sell on sunday

To find out how many cups Lin sells on Sunday, we need to determine the temperature on Sunday and then use it to calculate the corresponding number of cups sold. Given that the temperature on Sunday is 6 degrees warmer than Saturday, let's assume the temperature on Saturday is represented by t. Therefore, the temperature on Sunday would be t + 6. Using the equation provided by the computer company, c = 2t - 89, we can substitute t + 6 for t: c = 2(t + 6) - 89 Simplifying the equation: c = 2t + 12 - 89 c = 2t - 77 Now we have the equation to determine the number of cups Lin sells on Sunday, represented by c. Therefore, Lin would sell **2t - 77 cups** on Sunday, where t represents the temperature on Saturday.
