Answer: 7. 2n + 162 = 424

8. 3 hours

9. K ≥ 18

7. The number of Delicious apples sold is represented by n. Because they sold 162 more Empire apples than Delicious apples, the number of Empire apples sold can be represented by (n + 162). The total number of apples sold was 424, so the equation is Delicious apples + Empire apples = 424.

$n + (n + 162) = 424\\\\n + n + 162 = 424\\\\2n + 162 = 424$

8. The equation is given for this problem. Simply solve for h in the equation.

$55h + 275 = 440\\\\55h = 165\\\\h = 3$

9. The term "at least" generally means greater than or equal to. Thus, since Suzy scored at least 18 points, she scored 18 or more points.

$K \geq 18$

A hiker begins in a valley at 150 feet below sea level. When the hiker reaches the highest point on the trail, he is 579 feet ab

RoseWind [281]

We have been given that a hiker begins in a valley at 150 feet below sea level. When the hiker reaches the highest point on the trail, he is 579 feet above sea level. We are asked to find change (in feet) in elevation of the hiker.

To find change in hiker's elevation we will subtract hiker's initial elevation from hiker's elevation at the end of trail.

$\text{Change in elevation}=579--150$

We are subtracting negative 150 because at the beginning of trail hiker was 150 feet below sea level.

$\text{Change in elevation}=579+150$

$\text{Change in elevation}=729$

Therefore, the change in hiker's elevation is 729 feet.
