Which equation can be used to find the answer?


Christina climbs to the top of Mount Graham in Arizona. On the first day, she climbs to an elevation of 1029 ft. The elevation of Mount Graham is 10,724 ft. How many total feet of Mount Graham’s elevation does Christina climb on the other days?

Ae + 1029 = 10,724

e = 9695

9695 ft

Be = 1029 · 2

e = 2058

2058 ft

Ce = 10,724 ÷ 2

e = 5362

5362 ft

De – 1029 = 10,724

e = 11,753

11,753 ft
