Answer:
minimum of 13 chairs must be sold to reach a target of $6500
and a max of 20 chairs can be solved.
Step-by-step explanation:
Given that:
Price of chair = $150
Price of table = $400
Let the number of chairs be denoted by c and tables by t,
According to given condition:
t + c = 30 ----------- eq1
t(150) + c(400) = 6500 ------ eq2
Given that:
10 tables were sold so:
t = 10
Putting in eq1
c = 20 (max)
As the minimum target is $6500 so from eq2
10(150) + 400c = 6500
400c = 6500 - 1500
400c = 5000
c = 5000/400
c = 12.5
by rounding off
c = 13
So a minimum of 13 chairs must be sold to reach a target of $6500

Estimation is never an effective way to get the answer. But it's always an effective way to determine whether the answer you calculated is reasonable, or from orbit by way of left field.
For this case we must convert 34 miles to feet and inches.
34 miles to feet:
Jada runs 179,520 feet
34 miles to inches:
Jada runs 2,154,240 inches
Answer:
Jada ran 179,520 feet
Jada ran 2,154,240 inches
