To justify the expense of the membership fee, Joyce needs to visit the zoo enough times that the total cost of individual visits becomes higher than the cost of the membership plus discounted visits.
Let's calculate the cost of individual visits: $45 each.
To calculate the cost of the membership plus discounted visits, we first need to subtract the discounted visit cost from the membership fee:
Membership fee: $50
Cost per visit with membership: $20
$50 - $20 = $30
Now we can divide the membership fee by the cost difference per visit:
$30 / ($45 - $20) = $30 / $25 = 1.2.
To make sense of the result, we must round it up since Joyce cannot visit the zoo a fraction of a time. Thus, Joyce would need to visit the zoo at least 2 times to justify the expense of the membership fee.

Joyce wants to go to the zoo with her friend over spring break. You can pay $45 to get into the zoo each time, or join a membership for $50 and then only pay $20 each visit to the zoo. How many times will Joyce need to visit the zoo to justify the expense of the membership fee? (1 point) O 10 5 3 2
