Craig wants to use an elevator to carry identical packages having the same weight. Each package weighs 4 pounds and Craig weighs 90 pounds. If the elevator can carry a maximum of 330 pounds at a time, which inequality shows the maximum number of packages, n, that Craig can carry with himself in the elevator if he is the only passenger?n ≥ 60n ≤ 60n ≤ 236n ≥ 236 |

Answer» Given: WEIGHT of each package = 4 pounds Weight of Craig = 90 pounds Number of maximum PACKAGES = n Maximum weight that the elevator can carry = 330 pounds To FIND: The correct ineqaulity. Solution: The total weight of Craig and n packages must be less than or equal to 330, as the maximum weight that the elevator can HANDLE is 330 pounds. 90 + n*4 ≤ 330 4n ≤ 330- 90 4n ≤ 240 n ≤ 60 Therefore the correct option is (B) i.e. n≤ 60. |
