Leisure Centre currently has 300 members. The centre's management board wants to expand the facilities. The board has decided to raise the cost of annual membership from the current price of $400. A survey has found that for each $20 increase in the annual fee, 10 members will not renew their membership. Prepare a report for the board of CA Leisure Centre, advising them of the cost of annual membership that will maximize the revenue. (Hint: Revenue = Cost x number of memberships)

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.
