slope is $0.10            <em>($1.00 per 10 tokens = $0.10)</em>
y-intercept is $60    <em>($60 is the annual fee)</em>
y = .10x + 60            <em>(y = mx + b)</em>  
domain is x ≥ 0        <em>(you can't buy a negative number of token)</em>
range is y ≥ 60        <em>(input the domain (x ≥ 0) to find the range)</em>
Answer: the y-intercept of the function is $60 
 
 
        
                    
             
        
        
        
Answer:
130
Step-by-step explanation:
2(4x - 3) + 6(3y - 5)
2(4 × 5 - 3) + 6(3 × 7 - 5)
2(20 - 3) + 6(21 - 5)
2(17) + 6(16)
34 + 96
130

check your calculator for the [!] factorial button.
also bear in mind that most calculators also have an [ₙPᵣ] button, to get Permuations, and you can just use that.
