x = number of miles
Cost of company A = 0.09x+50.50
Cost of company B = 0.14x+60.50
Subtract the two expressions (B-A) to find the difference in price
B-A = (0.14x+60.50)-(0.09x+50.50)
B-A = 0.14x+60.50-0.09x-50.50
B-A = (0.14x-0.09x) + (60.50-50.50)
B-A = 0.05x+10
It would be the third equation.
4 balls for children plus the 5 balls for herself plus the accessories for 9.45 all together is 28.71.
Subtract the 9.45 from the total cost then divide by 9 to get the cost per ball

Write an equation system based on the problem
We can write the equation for "Twice the price in Japan minus five times the price in India is $20.60" as
∴ 2j - 5i = 20.6 <em>(first equation)</em>
We can write the equation for "Thirty cents less than three times the lowest price is thirty cents" as
∴ 3i - 0.30 = 0.30 <em>(second equation)</em>
Solve the equations
First, solve the second equation to find the price in India
3i - 0.3 = 0.3
3i = 0.3 + 0.3
3i = 0.6
i = 0.6/3
i = 0.2
Second, solve the first equation by subtitution of the value of i to the equation
2j - 5i = 20.6
2j - 5(0.2) = 20.6
2j - 1 = 20.6
2j = 20.6 + 1
2j = 21.6
j = 21.6/2
j = 10.8
The price in India is $0.20 and the price in Japan is $10.80
