Kate wants to buy gifts for her family. She needs to buy 9 gifts and each one costs \( \$ 15 \). She earns \( \$ 12 \) per whole hour when she babysits. How many hours will she have to babysit to earn enough money for the gifts?

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

If \( a=5.6(1 \mathrm{dp}), b=24.1(1 \mathrm{dp}), c=145 \) (3sf) \( \mathrm{d}=0.34(2 \mathrm{dp}) \) Calculate the upper \& lower bounds to \( 3 s f \). \( {c d^{3}}^{3} \)

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

10) A loaded truck travels 14 km in \( 25 \mathrm{minutes} \). If the speed remains the same, how far can it travel in 5 hours?
