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)

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.
