ket (1), the total cost for the broker's services is calculated by the expression below.
$0.50t + $5.00
How much does the broker earn by selling 12 tickets?
For the first day we have the following function: f (n) = (0.3 * 10) n + 8 For the second day we have the following function: f (n) = (0.4 * 10) n + 5 You spent the same amount of money as the day before: (0.3 * 10) n + 8 = (0.4 * 10) n + 5 3n + 8 = 4n + 5 n = 8-5 n = 3 items We evaluate each function for n = 3 f (3) = (0.3 * 10) * 3 + 8 = 17 $ f (3) = (0.4 * 10) * 3 + 5 = 17 $ The total amount of money is: 17 + 17 = 34 $ Answer: you purchase 6 items you spend at the craft store during the sale $ 34
