Question Cooper was out at a restaurant for dinner when the bill came. His dinner came to \( \$ 28 \). adding in a tip, before tax, he paid \( \$ 33 \cdot 32 \). Find the percent tip.

8. A gym membership costs \( \$ 20 \) per month plus a one-time regstration fee. If you poid a total of \( \$ 180 \) after 6 months, how much was the regstration fee?

3.1. Simplify each of the following ratios: 3.1.1. \( 4: 28: 16 \) 3.1.2. \( 6: 1.25: 2.5 \) 3.1.3. \( 3.6: 27: 13.5 \) 3.2. Distribute \( R 24000.00 \) in the ratio 2:1:5.

Simplify \( 6+3 \times 5 \) \( 20-7 \times 2 \) \( 4+5 \times 4 \)

(ii) \( \begin{array}{r}5.129 \times(-0.15) \\ .23 \\ 5.129 \times 6\end{array} \)
