- t = d/s
- t = 7/8 : 3/8 = 7/8 * 8/3 = 7/3 = 2 1/3 min
 
        
                    
             
        
        
        
You're given a table of x values and an equation. To solve, plug in the values for x.
First box: y=2(-3)-1=-7
Second box: y=2(-2)-1=-5.
See if you can solve the third one.
        
                    
             
        
        
        
Answer:
   11.4 years
Step-by-step explanation:
We assume you want to know the time it takes for Lucy's investment of $1200 to have a value of $6400. The compound interest formula is good for finding that.
   FV = P(1 +r/n)^(nt)
for principal P invested at rate r per year for t years, compounded n times per year. We want to find t such that ...
   6400 = 1200(1 +0.15/4)^(4t)
   16/3 = 1.0375^(4t) . . . . divide by 1200
   log(16/3) = 4t·log(1.0375) . . . . take logarithms
   t = log(16/3)/(4·log(1.0375)) ≈ 11.4
It will take about 11.4 years for Lucy's investment value to be $6400.
