Algebra

1. Suppose you and a friend are working for a nursery plating trees. Together you can play 8 trees per hour. Qhat is the greatest number of hours that you and your friend would need to plant at most 40 trees?

$$\small{ $ \dfrac{ 40 \text{ trees } } { \dfrac{ 8 \text{ trees } } {1\ h} } = \dfrac{40}{8} = 5\ h$ }$$

2. The Garcias are putting a brick border along one edge of their flower garden. The garden is no more than 31 ft long. If each brick is 6 in. long, what is the greates number of bricks needed?

$$\dfrac{ 31\ ft * \dfrac{12\ in }{ 1\ ft } }{ 6\ in } = \dfrac{31*12}{6}= 62\text{ bricks}$$
