A cargo elevator has a maximum carrying capacity of 400 pounds. If each cargo box weighs 25 pounds, what is the maximum number of cargo boxes that the elevator can hold?
Please Help!

16

Step-by-step explanation:

400÷25

=16

25×16

=400

option 1 is correct.

step-by-step explanation:

y varies inversely with x and constant of variation is 4

the equation will be:

y = k/x

where k =4 so,

y = 4/x

if we put values of x of option 1 in the above equation and find values of y

y = 4/-2 => y =-2

y = 4/-1 => y = -4

y = 4/1 => y = 4

y = 4/2 => y =2

so, all the values of x and y are correct.

if we put values of x given in other options and find value of y we cannot find whole table satisfying the equation.

hence option 1 is correct.

good luck on your studies! : )
