Question

The class found a treasure chest full of candy. It contains 1000 pieces of candy which each weigh .121 pounds. The chest itself weights 92 lbs. If each student can lift 71 pounds, how many students are needed to lift the treasure chest filled with candy?

Answer 1

Three students will be needed to lift the chest.

Explanation:

Multiply the weight of each piece of candy by the number of pieces. Add the weight of the chest. This will give you the total weight of the chest and candy. Then divide by `92` pounds per student to determine how many students are needed to lift the filled chest.

`"total weight"=1000color(red)cancel(color(black)("pieces"))xx(0.121"lb")/(1color(red)cancel(color(black)("piece"))) + "92 lb"="213 lb"`

`"no. of students needed to lift the filled chest"=(213color(red)cancel(color(black)("lb")))/((71color(red)cancel(color(black)("lb")))/("1 student"))="3 students"`

Three students will be needed to lift the chest filled with candy.
