As per the problem
The chemicals in my swimming pool use a ratio of 5 tablets of chlorine for every 14 days.
we have been asked to find
Which ratio shows the number of chlorine tablets needed for 42 days?
Since for each 14 days the number of tablets required is 5

A) write an equation you can solve to find the cost of one ticket
x=cost of one ticket.
9x+5=104
b)
I have to solve this equation.
1)adding -5 to each side
2) dividing both sides by 9
c)
9x+5=104
1) 9x+5-5=104-5
9x=99
2) 9x/9=99/9
x=11
the cost of each ticket was $11
