Question

a florist shop represents its first months sales with the equation \\(y = 168x + 8\\), where \\(x\\) represents the number of days that the shop is open and \\(y\\) represents the sales in dollars. the owner of the shop would like to calculate the number of days it took to reach \\(\\$3,200\\) in sales. which would be used to solve the problem?

substitute 3,200 for \\(x\\).
add 8 and 3,200.
divide 3,192 by 168.
isolate \\(y\\) in the equation.
