Part B A tie-dye kit with one T-shirt costs \( \$ 15 \). Each additional T-shirt costs \( \$ 4 \) more. Choose the recursive formula to represent the situation. \( \begin{array}{ll}\text { A. } a_{n}=a_{n-1}+4 ; a_{1}=11 \\ \text { B. } a_{n}=a_{n-1}+4 ; a_{1}=15 \\ \text { C. } a_{n}=a_{n-1}+11 ; a_{1}=15 \\ \text { D. } a_{n}=a_{n-1}+19 ; a_{1}=11\end{array} \)

Factor the polynomial function \( f(x)=4 x^{3}+20 x^{2}+29 x+10 \) Note: Write \( \left(x-\frac{a}{b}\right) \) as \( (b x-a) \) The zeros are \( f(x)= \)

23. REASONING A student theater charges \( \$ 9.50 \) per ticket. a. The theater has already sold 70 tickets. Write and solve an inequality that represents how many more tickets the theater needs to sell to earn at least \( \$ 1000 \). b. The theater increases the ticket price by \( \$ 1 \). Without solving an inequality, describe how this affects the total number of tickets needed to earn at least \( \$ 1000 \).

Find \( \sum_{i=3}^{7}\left(-\left(-\frac{1}{3}\right)^{i-1}\right) \) First write out the summation: Find the answer:

3 Реши задачу. Один гончар заработал 1300 тенге, а другой, изготавливая такие же изделия, - 1950 тенге. Сколько изделий изготовил каждый из них, если первый изготовил на 2 изделия меньше, чем второй?
