Answer:
 40b - 4b    or 36 b 
Step-by-step explanation:
No. of tomatoes in each box = 40
No. of box shipped = b
No. of tomatoes in those b box = b*No. of tomatoes in each box = 40b
No. of tomatoes damaged in each box = 4
No. of box shipped = b
No. of tomatoes damaged in those b box = b*No. of tomatoes damaged in each box = 4b
Thus, total no. of tomatoes that can be sold by store = No. of tomatoes in those b box - No. of tomatoes damaged in those b box  = 40b - 4b
Algebraic expression to express the no. of tomatoes that can be sold from those b box is 
 40b - 4b = 4b(10-1) = 4b(9) = 36b (Answer)
 
        
             
        
        
        
Answer:
$1226.78<x<$1301.22
Step-by-step explanation:
The formula for calculating confidence interval is expressed as;
CI = xbar ± z×(s/√n)
Given
Mean (xbar) = $1264
z is the z score at 90% CI = 1.645
s is the standard deviation = $150
n is the sample size = 44
Substitute
CI = 1264±1.645(150/√44)
CI = 1264±1.645(150/6.63)
CI = 1264±1.645(22.624)
CI = 1264±37.22
CI = (1264-37.22, 1264+37.22)
CI = (1226.78, 1301.22)
Hence the confidence interval of the mean is $1226.78<x<$1301.22
 
        
             
        
        
        
Ok so first you take $64.80 and multiply it by 2.5. You get $162. Now take $162 and subtract $20 from it. You are left with $142.
