Final answer:
To determine the number of special exhibits for which the total cost with a membership is no more than the total cost without a membership, set up an equation and solve for x.
Step-by-step explanation:
To determine the number of special exhibits for which the total cost with a membership is no more than the total cost without a membership, we need to set up an equation.
Let's assume the number of special exhibits is x. If you are a member, the total cost would be $80 (membership fee) + $10 (cost per special exhibit) * x. If you are not a member, the total cost would be $20 (cost per special exhibit) * x.
We need to find the value of x for which the total cost with a membership is equal to the total cost without a membership. So, the equation is:
$80 + $10x = $20x
Solving this equation, we can find the value of x.
